r/shopsmith

I acquired this Shopsmith last night and just started researching its history. Some things don't line up yet, so I'd like your thoughts on the model and history.

The plate shows that it's a model ER, but the serial number is 35155, which doesn't look like it's in the ER date range on the Shopsmith website chart.

There's no housing for the pulleys and belt, but most ERs I've seen have one. The model 10E did not have a belt housing in the images I've seen, but this clearly says ER.

Accessories - it has the extended table, saw table and blade, and disc sander, but it's missing the lathe pieces. No manual.
