Oh well, another "story" and again, cannot be confirmed...as I have had over the years , conversations with folks from the factory ( through Jeff M and my projects) and yes, the guy who supposedly worked with 41 Nuts son, and told me ,that he was the one who designed?? ( came up with ) the arbor type press to "be used in stead of "staking" and just pressing the medallions in place so as to NOT "break " them..Walter Howe and Jack Behn ,BOTH told us, that in the early days, the stags were fatter, and they had trouble putting the medallions in due to this as they tried to be located more to the rear, ala the wood and plastic (hard rubber) so the suppliers had to :lower" ( remove more material on the down slope . from the center of the grip panel , towards the front, thus making it "flatter in the medallion area..so , finally , that doen , they could locate the medallion in a more "permanent" location, and be the same , grip, to grip ( the so'called' 5/16"s?? or whatever).unlike the Colt grips , where they did NOT install a medallion, so could stay "fatter" ( meatier...) more to hold onto, and as pointed out by JD, the different 'suppliers' of grips)..........of course the stems were not long enough to be used "properly" on this type of grip panel.......yep...just some more stories, ( Ruger lore...) and until can be documented and JD has come about the closest as anyone can......it will remain just that, subjective, argumentive and another opinion...some of these guys are LONG dead and gone, the ones 'still'around today are "how old...?? and they did NOT see and do "it all......." ( Mr Ruger is GONE...) so I cannot nor will not, call any of them "liars" , just another page in the book of life in the manufactruing world, sadly Mr Ruger never wrote ANY of this down, unless he had to ,for patent applications.......
and Radical, the trouble with your 'thought' ,as to so many are "still out there..." is that how many MORE have been added all these years, and still being "added" today, and what rate.......don't add up.........and the 'San Bar' stag of today, is NOWHERE near the"domestic' stag that was used back in the late 40's and through the 50's..........different characteristics .........
