Sounds like a good knock around gun, well suited to outdoor use with less than scrupulous cleaning and oiling in the field. A sort of modernized version of the Colt Commando .38 of WW2.
I've seen photos of Green Berets and SOG carrying the Colt Python in the field, and a friend who was a medic in Nam carried a Colt .38 his dad sent to him.
While not a gun guy my friend also carried a Webley .380 when he returned stateside and worked at an emergency room in a bad neighborhood.
If the matt finish bothered the owner they could apply baking laquer finish.
I would first find out if the laquer could be removed at a later date without damage to the original matt finish.
