Vintage Simmons Drums (UK) Users Group

Hi all! I was just recently given a set of Simmons SDS7 drums, un-
opened, brand new. The gentleman that gave them to me said he 
believes they are from 1985! When I say new, I mean NEW!!!!! They 
have never been touched!!!!! Does anyone have an idea about their 
value? Any feed back would be a great help! Thanks, Bob.
