Fuzzy Farrant and John Hurst Grips get a lot of love from grip collectors but Guy Hogue grips do not get the same attention.
There was a set sold on Ebay some time ago that were identified as Farrant's but I think they were Hogue's based a the interior of the grips.
Guy Hogue used white chalk to identify the sides of the grips and
used a brass colored screw. Hogue also put a support fixture inside the grips.
I believe the following are Hogue's.
#1 I believe these are a very early set with out the inside fixture but has the brass screw and white chalk.
#2 a later set with inside fixture.
#3 is for a Colt E/I frame with a letter
#4 J frame has white chalk and inside fixture
Also note on 2,3 and 4 the high wood on the right side of the grip that continues today.
