Looks like a student aluminum model.

...as pictured HERE in the 1979 Slingerland catalog.

That is Indeed a 60's model Slingerland Aluminum student Model snare drum, they came in either an eight lug or ten lug model, the 60's models alot of the time have brass rims on them which is a plus, also some models have an Internal lug support brackets as to help support the thin aluminum shell and some don't have them, the ones that do have the lug supports sound different from the ones that don't , the pics I've shown you are a ten lug 60's model I own this one has brass rims and the Internal lug supports, the link you were provided with doesn't have the Internal lug supports.

As always, thanks vintagemore200 - what's a fair price for these?

the price it's listed at is the going range to about $120.00 is it 8 or 10 lug? I personally wish I would have kept the 8 lug model. I've had both.
