Stock adjustment hammer gun

[bob lyons]

In a previous post i was looking for info on a hammer gun I have. I received my research letter and it was sold to Folsom which was nice .
I brought the hammer gun down to a gunsmith and he thought it would be fine to shoot.
The problem I now have is the drop at the comb and heel of the stock is very low.
I noticed in some of the hunting photo’s that some of you guys have a sleeve on the stock and wanted to know if that may help me to get a better fitting gun.
Please give me any feed back and reference of a manufacturer for a sleeve that you have had experience with.
