I called Bob Runde shortly after I got my R6. I had heard the same Szamboti thing. If Barry has records, I believe him that his father sold some to Bob. Bob laughed when I asked him about Szamboti forearms and stated he made all of his. Tate relayed the longer point info to me and also mentioned he thought the straight grain forearms where/are likely Gus's. Mine is straight grain and yellowed from time, but my points are the same distance to the joint ring as the butt sleeve, IIRC.
Bob was a machinist for a horn company and setup McD's machines for them back in day. He had a number of years under his belt making cues before he set up Schon with Terry.
