Is this the one on ebay? I saw that and asked for verification, no response. I would make certain before doing anything on this one. I also saw one on C/L and I am almost certin it's not a Jupiter, even sellers says it is. He has yet to provide good clean pix, the ad pic is too vague to tell if it is a Jupiter, but looks like a regular COS.

The only way I know is to get a picture and verify it. I don't if they made COS Jupiters. I thought they were all COB, but then I have not owned one....yet.

The Ebay one isn't listed as a Jupiter-he just says a magnet doesn't stick to the "frame".

If it's this one that your talking about - I bet 100 clams that it's COS. I have the identical one to this and love it- use it live often- great drum- but not a COB. This one is a 79-81 COS

Jupiters most often have a distinctive parallel strainer - that huge, boxy looking mechanism.

Well,here is why I'm asking.The catalog scans show one year with the steel shell having 2 lines,and Jupiter referring to the COB shell,not the snare mechanism.Jupiters having 3 lines,5 or 6 1/2 tall and either snare mechanism.I now own at least 4 steel snare drums-that is way enough.

I saw in the 1980 (I think it was 80) catalog that same thing- where most of the chrome snares on the chart were actually COB- only one was COS. They clearly showed that it was possible to get a COB without the big parallel strainer. IF you can find that you would have the best of both worlds- a lighter and more simply designed COB. BOL - I hope you canExcited
