There was a post-war rebuild program for Colt Commandos and quite a few had their original 4-inch barrels swapped for 2-inch. The rebuild program for Victories did not change the barrels unless it was a new 4-inch barrel for one that was damaged or worn out. Also, the top strap markings would have been changed to the then-current Ordnance standard. The OSS was disbanded immediately after WWII and they did not use 2-inch Victory Models during the war.
It's a cause for some regret when that happens, but if it extends life for an old veteran then the purpose is served...

I totally agree with you, if the firearm has a historical justification for having been modified, it would be interesting and then collectible for my point of view.
But what I wrote is justified by the law on firearms in Italy.
Here, the law on firearms provides five large categories divided as follows:
1 HUNTING FIREARMS
2 DEFENSE FIREARMS
3 SPORTING FIREARMS
4 WAR FIREARMS
5 ANTIQUE FIREARMS
in addition, you can request a firearms collection license.
Every firearm on the market is part of one of these 5 categories.
Hunting firearms can be had in unlimited quantities, all rifles are considered hunting, only full auto ones are prohibited, the 22 LR calibers are not hunting firearms but sports firearms .
Self defense firearms , are allowed in number of three.
Sporting firearms between long and short you can have 12.
War firearms, prohibited. Very few war firearms collection licenses in all of Italy, there will be less than ten people with such authorization, all issued before 1970, and never granted again.
Unlimited antique firearms .
A collection license is given to those who want to have a greater quantity than the permitted 3 defense firearms and 12 sporting firearms , since all rifles are considered hunting firearms and therefore unlimited.
For example, I have a collection license and I own more than three hundred firearms , almost all pistols and revolvers. You cannot take the firearms in the collection out of the house unless you ask for authorization. The others ouside the collection you can take and use at the shooting range or in the countryside.
Therefore, given the limitations, I purchase firearms that deserve this name of COLLECTION FIREARMS.
