Vintage Simmons Drums (UK) Users Group

Hi, all:

I recently acquired some SDSV pads from the following ebay listing:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200347297113

I know that the SDSV shells started out as transparent, and the insides were then painted, but does anyone here know whether any of these pads were originally shipped/sold without paint? I've opened up one of the pads (the one with the hole in the surface), and, unless someone did an excellent job of removing the paint, it looks like these never were painted. 

Thanks,
Jim Stewart
