Well put Roger.
As we continue with this hobby, we will encounter more and more reworked and parts switched out rifles. Almost like detective work when picking up and examining a rifle.
In recent times I have other collectors bringing me their purchases for a check up and evaluation. I have noted that there are many full wood rifles floating around on the market that are quite obviously 'restored' by civilian owners. As most know, there is more to stocking up a Lee Enfield than just getting the barreled action to fit into the wood and getting the bands and handguards to fit.
Now when I look at a rifle that I might buy, I look for the signs. Same as in the world of collecting antique furniture , or cars, motor cycles or farm tractors.
I just find it ironic that some of the same commercial outlets that were profiting by selling mil spec rifles to the public converted into sporters, are now profiting by selling woodwork and parts to restore them back.
