Jerry asks wise questions

refinished many shotgun stocks back in the day

never had a problem with re-checkering after sanding off
old checking but have an expert look at the gun in question

if the stick is nice enough there are tricks,
including sawdust and glue to fill an extra deep scar or two

if the gun isn't worth restocking then talk to whomever you
want to recut the checkering and see what they think

best wishes
