FROM THE HAWKEYE GIRLS' LAIR;........The referenced post type two piece mount was Bushnell's Phantom Scope Mount #76-2928. Mine came from the secondary market and one has to watch EBAY for them. These were termed "all purpose" and were a (pair of) "V" block bottom mounted on any level surface round or flat, and locked to two (one screw/stud for each mount) hardened chrome molybdenum steel studs seated in the two factory tapped 6-48 holes on the top rear of the Hawkeye's barrel. Bushnell called out that the studs only required normal screwdriver tightening pressure and the mounts were to be used for no recoil greater than the 38 Special caliber.
BTW, I have multiple rigid base sets for the Hawkeyes in the big steel box, yet none of the rigid one piece mount boxes has a Bushnell catalog number on it, nor is there a number on the small information and install instruction sheet.
If any of you need a copy of the instructions for either the rigid mount or the two piece mount set, I would be happy to send to you. PM me and I will give you my PO Box and you can send me a SSAE for me to return the info copies to you. Sorry, I seek these quietly, so none of mine are currently for sale. However, the info sheets would be a start for you and are usually missing when you finally find the physical parts........
Last, RE: your question on value......I think a complete set: screws, base, instructions, small stop block for secure mount of the Phantom scope, 1.3X or 2.5X scope, long or short version, have to run at least $175 to 250 and frankly, based on completeness and age, 1963!!, maybe more. As noted in the Southern Ridges, "Holler back" if any questions........There have been more than 55 Hawkeyes thru this grinder, and even tho John Dougan told two of my Stalwart Friends in Tulsa, that "Splitz doesn't know sh*t about Hawkeyes", I suspect I could help write that chapter in his book(s) for him, with no need for revisions......... 8) :wink: After 71 cranks on the Big Guy's calendar and 41 of them in the Ruger Collector Harness, I'd be letting all of you down if I did not call it like I see them, everyday, and share information as I promised all of those who mentored me, some decades ago........... :lol:
