Hi,

My grandfather just passed and he has literal shelves and boxes full of music, almost all brass band performances, (plus some recorded shows), etc on VHS and Cassette. These span decades and his own music recording of brass band live shows and many are very likely unique.

The commercial tapes and the recorded shows probably exist elsewhere in better mediums, but many of the live show recordings are his own recordings and don't exist anywhere else. Decades of unique brass band history.

Is anyone interested in taking these, as otherwise they'd probably just be thrown away? They're currently located in Atlantic County, New Jersey but my family is willing to mail many of them media mail to other parts of the USA if there's someone interested. We can work with them to High-grade them if so.

There's also shelves and shelves of vinyl records, mostly brass band, I'm not sure what the plans are for those. Similarly boxes of sheet music, but it sounds like my aunt knows a sheet music preservation society.

It'd be a shame to lose all this but I don't have the capacity to deal with it.

Thanks!

Bit of a miscommunication and return window missed. Our loss your gain.

Brand new in box Sony FE 100mm f/2.8 STF GM OSS, not the macro version.

I popped the lid (no security sticker) just for the photo but I didn't go any deeper. If you're a serious buyer I'm happy to take more photos taking it out further to show it's there, but I didn't want to disturb the packaging if I didn't get traction here and needed to sell it elsewhere to keep the factory new set up.

If I sold it at the going rate on ebay, after fees it'd be just a bit more than $1000 to me, so I figured I'd pass that on here to y'all.

Price: $1000 shipped CONUS. Shipping to other places can be negotiated, might stay free depending on where and how.

We can work out a small discount for local pickup.

I stuck my radiacode 103 in a 600 R/hr field to see what it did, knowing it's max dose rate is 100 mrem/hr.

I think this is an important lesson on knowing your equipment - if you saw "exceeding 100 mR/hr" you might think it's just over, and be OK doing spending time in the field for a short duration because 100 mR/hr dose isn't toooo scary in the grand scheme of things. But once fully saturated, the machine reads the same, no matter the dose rate.

At least it tells us it's saturated, unlike the "3.6R/hr" chernobyl issue. Every unit performs differently though - I put a CDV-700 in and it read 0 (it's pulse counting, and the pulses were so close together it measured the voltage as a flat line which is zero). I put a 451P in and it read 5 R/hr, but the only indication it was saturated was the "R/hr" flashes, which is hard to see, and you'd never know if you didn't read the manual.

If you're going to have a meter and rely on it for safety, know what kind of Radiation it can and can't detect. Know if it under or over responds to xrays or high energy photons. Know what the minimum and maximum detection threshold is. Understand and live by time distance shielding, the meter won't protect you, just help you protect yourself.

Where did I find this huge radiation field, and why did I get to play with it? If you let it, your garden variety General Electric OEC c-arm (fluoroscopic machine) found in every hospital, surgery center, and injection pain clinic easily gets to 1200R/hr...12 inches from the surface of the Imaging surface. Imagine the dose rate at the tube port (20cm from the focal point, vs the 70 cm that 12" is).

I've gotten Cath Lab machines up to 20,000+ R/hr before at 12 inches from the imaging plate. No wonder people come out of extensive intervention procedures with localized radiation caused erythema, epilation, and sometimes even desquamation.

Some background if you want technical details:

The FDA regulates medical xray machine performance standards, 21 CFR 1020.32(d)(2) specifies dose limits for fluoroscopic machines in R/min air kerma, which translates to crazy rates. These are measured at 12 inches because that's the typical "source to skin distance" (SSD, the distance from the focal spot of the tube to Patient skin) for the "reference man". However, FDA doesn't have any limit for "recording" your fluoroscopic images (fluoroscopic is technically supposed to be used for live view, while recording ("cine mode") is considered a form of "serial radiography", so a series of radiographic images in quick succession.

(to ease your mind, the machines basically never hit these dose rates, most issues are from extended procedures. They'll modulate via a mechanism called "automatic brightness control" or ABC. Also, the c-arm have 192V lead acid DC batteries that need to recharge after an extended exposure so you can't just stand in the pedal and cook someone, you have to tie them down and slow roast them. Cath labs/IR use massive UPS high voltage generators so their limiting factor is heat, but they're very good at Heat dissipation so they're scary. But if you're in the cath lab, they're worried about you dying on the table TODAY not any burns or leukemia down the road.)

Therapy machines are on a whole different level.

Tl;Dr. Know your equipments capabilities and limits and also respect xray machines, they can do crazy high doses if you let them.

(there's a reason why xray techs need a 2 year degree and a registry exam, plus advanced modality training and certification)

Being shared around in other communities, haven't seen it here yet

First from infinity to minimum focus, then 1 to 3 softness. Not pictured - the vast amount of medical tape used to secure it and turn the dials without sliding the unit around.

I took some x-rays of one of my camera bodies. Can you identify it? Really gotta know your differences between the bodies and their features. And see if you can identify the Minolta Rokkor lens too if you're feeling spicy.

Hints: You have to look really close at the details to see the differences between it and the SRT-101. First place to look and most obvious >!prism box!< second >!around the mount ring but it'll only narrow it down!< two other visible but more nuanced differences third >!rewind mechanism!< fourth >!backplate size!<. There's other differences but they're not visible because they're radiotransparent or blocked.

Solution: The body is the >!SR-T 102, (303 in Europe, SR-T Super in Japan)!< which you can tell because >!it's an SRT body with MLU mechanism, judas window, larger backplate size more complex film rewinding mechanism to allow for double exposures!<. You may be able to get the right answer with just a few of those. The lens is a >!Minolta Varisoft Rokkor 85mm f2.8!<.
