What does this FF and J28 mean (1943 long branch)

Thanks in advance for help.

I've always wondered who made this barrel and this is the only mark I can find on it, I know sometimes they would put a kanji on a part as an abbreviation of who made it.

If this mark means nothing I'll delete the post.

Thanks in advance for help.

Did Kokura arsenal or Tokyo arsenal make this?

Also what's going in with the grips, are they original or new ones that have been glued on, I think they were glued on.

Thanks in advance for help.

I'm using it on a Siamese m1 carbine training rifle, did Siam/Thailand use unique m1 carbine slings?

Thanks in advance for help.

How would I go about replacing the tritium vials in this, it lights up when I shine a flashlight or laser on it but that's the only way it will light up. The vials look to be glued in or soldered in so how would I get them out and back in. I saw an old reddit post someone was doing this but didn't explain how.

​

Any help appreciated

I know this is alot of text but if someone can translate or give me a general premise of what this says I'd appreciate it. AI doesn't do a good job of translating this, thanks in advance for help.

If not where are they from, if there's a way to tell? I'm putting a muzzle nut on a romanian AK. Thanks in advance for help.

I think 1959 but I could be wrong. This is copper jacket and the rest if my Iraqi .303 is cupro nickel. Is this rare? Thanks in advance for the help

I can't see a factory code, unless 82 isn't a date and is the code. Thanks in advance for info.

It looks like two Tula hammers crossed over eachother, has anyone seen this marking before and if so what is it? Thanks in advance for help. (1927 Ex dragoon Latvian refurb) *marking is on the barrel shank*

I was positive it was a repair depot in Riga but now I'm pretty sure I was wrong as m9130.info says its "unknown". Thanks in advance for help
