I'm most familiar with the RJ Reynolds/Grabow coupon pipes. When they stopped the program it was the longest running program of that type. Besides the Grabows available they also had the Adventurer,which was Grabow made, and was available with coupons from Madiera Gold. Here's a price list from 1969.
Grabow also made some pipes for Amphora using mostly Grabow shapes but stamped with a different ( 3 digit) shape number.
Stan, I've never had a full pocket tin of PA. Do have a tin of Velvet that Dave Whitney sent me that I think is from the 60's- early 70's.
