From most info, I guess any of the pads which were in production when the gun was made will be right. Thanks for you replys

Can anyone tell me which recoil pads were used on late A Grade 20 Ga.guns.
I just found one and it has a standard butt plate, but is just a bit short for me. I think a correct recoil pad could make a big difference in the way I shoot it.

Thanks
