I want to agree with Jim Watson that it looks like a special production gun, but how can we be sure?
I'm always interested to know about a gun's proof date code.
I realize that you said that you bought it about 20 years ago, but when was it made?
What's the proof date code, 2 letters inside of a box?
If you bought it new, which vendor sold it to you?
Is it possible that someone had it chrome plated or electroless nickeled, or could some of it be stainless?
Usually where there's one production model, there will be more.
But they're not always easy to find or learn about.
Without more to go on about who imported it, and possibly asking them for info., I wonder if Pedersoli
could provide information if they were given the serial number, date code, and sent a photo by email.
Back in the days when Navy Arms was a big importer of Pedersoli guns, the owner of the outfit named Flintlocks Etc...
in Richmond, MA was a primary Pedersoli import agent for them.
I think that his son runs the company now, and perhaps an email inquiry to him may provide some clues.
If it's German silver and not plated, and it's factory production, then someone "somewhere" should remember details about it.
But I also want to know why you described the barrel as chromed?
Could it simply be a high polished finish that someone performed on a kit?
The finish in the photos of many surfaces does look uniformly matte.
The pistol in this link was mirror polished with Mother's Mag & Wheel Polish yet is looks like chrome or stainless.--->>>

I wish that we could see more close up photos of the various metal surfaces such as the frizzen face.
For instance the color match between the barrel, ramrod ferrule and under-rib look perfect much like electroless nickel.
Do the surface colors match across the whole gun?
I would certainly appreciate knowing more details and seeing close-up photos of such a fine looking gun to more closely compare the surface colors and finish.
I can't see the ramrod entry pipe very well either.
It's a real beauty and Jim Watson could very well be correct about it being a factory production.
But even if factory made, what kind of finish and/or steel is it?
Is it rough or textured at all?
A slippery matte finish suggests electroless nickel and not chrome, but who knows?
