I was in a guitar shop the other day and the luthier that owns it now bought the business from the guy who opened it in 1965, the original owner was Whitey Lunzar.
In chatting with the current owner he mentioned that Whitey sold a lot of Rogers, Slingerland and Ludwig drums back in the day and that he might have some boxes of NOS and used parts down in the basement. It's a small one man operation so I'm not getting too excited but you never know...
I told him that if he digs them out I will sort them and bag them for him.
Could be trash... could be treasures... he said he would be very happy to sell anything in the boxes that anybody wants.
I'll see what surfaces and post some pics.
