Homeless, I am a bit confused . I have opened and viewed the catalog you reference, but do not see the guns you reference on the pages you suggest.
On Page 10, I see a top rib extension with Greener type cross bolts with either square or round bolts. No screw grip there.
On Page 9 , I see the Premier Hammer gun with the Scott Improved bolt which is a Greener type , rectangular, cross bolt. No screw grip there.
On Page 19, I see a plain quality Greener gun with a rib extension, but no screw grip.
On Page 24 , there is a falling block action-----no screw grip
Is it possible you referenced the wrong catalog ?
