i have a first run acro welded seam that im restoring its a orange peal but is there proof on that drum i dont know is there any paper work on it ?
Rob Cook's Ludwig Book p246 mentions the welded seam on prototypes and has a photo of one which has all aluminum lugs and hoops. Do the other production details suggest yours is early 1963? or pre 1963? Or are you asking about the "orange peel" finish?
i sold a suppose pre proto type cos 3x 13 jazz snare with keystone and it did not list until 72 cat so no early on mention of it no proof i only only got 350 for it should of kept it but cant collect all the drums in the world
Those nice COS ones? It's called a Piccolo. Catalogs don't come out every year and they aren't always right up to date so production drums can appear for sale before they appear in a catalog. I see the metal Piccolo in the 1972 catalog and not in the 1967 catalog (looking at the Clay Greene scans). So all that tells me they came out some time in between. The aforementioned Rob Cook book says they came out in 1970 so a keystone badge would be an early one but not necessarily a prototype. Others may know more about that.
Here are instances I've recorded of a keystone one turning over in my database:
Ludwig 3x13 Metal Piccolo KS675787 pristine $512.00 11 bids eBay 20-Mar-08
Ludwig 3x13 Metal Piccolo KS482016 pristine hazelshould $615.00 17 bids eBay 29-Mar-08
Ludwig Piccolo 3x13 ks625402 $406.61 31 bids eBay 15-Feb-09
So your $350 may be a bit low, but not so bad if you sold it in the depths of the Global Financial Crisis or 10 years ago. It depends on context and the condition it was in.
I'm a bit suspicious that my serial number of 482016 may have been a data entry error. I'll go and crosscheck what I can to find out. It would certainly be a very early one! *** edit *** I'd be happier if it were 68 rather than 48, but I can't find anything to cross check...other than hazelshould is a good seller and he did seem sure that it was 1967.
