Pinseeker Irons/Woods?

[DonW]

My BIL just died and my SIL gave me his bag of clubs. He was the kind who generally had to have the best of everything, they are at least 15 to 20 years old and have a small cavity in the irons (which look like they are cast), the 11*driver is very small head, fairways are #3 16* and #5 22* (driver and fairways are metal) and everything is stamped 350 RS (even the shafts are labeled as such). Digging on the internet I found reference to Arnold Palmer having played Pinseekers during his career, another little blurb stating Pinseeker introduced metal woods to the marketplace, the company being sold to another golf co. around 7 years ago and then nothing. They look nicely made and have very little wear on them but I have no idea what to expect when I try them out. Anyone have any further info or input as to what these were in their day?
