tomis, I believe that is a pistol that was built on the same receiver as the scout rifle.
However i have never seen an engraved nickel plated one, most were blued steel and brass.
If you remove the forearm, there should be a allen head bolt which holds the barrel to the receiver.
It can then be disassembled down to trigger assembly, receiver and barrel.
It did come from the factory with a ramrod. It has a unique nipple which screws directly into the barrel, and uses a #11 cap.
Sorry, but I have no idea of the value, could be of moderate value to a collector.
You may be able to download the manual from Thompson Center, not sure.
Hope this helps some. TC
