Your guess on pistols nationality

[Relic shooter]

As mentioned previously my 'European Gun Makers library hasn't turned up since downsizing to smaller home so back again.

Based on past experience & enclosed photos i think we can all agree this nicely made pistol with it's original iron ramrod started life as an 'early' flintlock.
We usually only see early European flintlocks without bridles on the tumbler, unless they are of lesser quality than this pistol.
Closeup photo of the lock shows screw hole where the frizzen was mounted & filled.

Closer examination indicates that the lock's original hammers base may have been used by forging a percusion nose to make the conversion..
Percussion conversion was done with a snail type drum screwed into the touch hole area & fitted to the old pan's recess.
Judging from past collecting experience this pistol appears military with it's .64 cal. smooth bore & skull cracker butt pin, maybe custom for officer due to carving ?
Surprisingly the wood, bore & breech remains in excellent shape.
QUESTION !
Any ideas on the HP & Crown type markings shown on the breech area photo ???
Kinda resembles the Danish / Austrian style ?
Appreciate hearing what you all think.
Best regards,
Chuck/Relic shooter

I believe the mark HP with crown over is French. I'll have to dig out my Gun Marks book to check, may take a while though.
Edit: I found my book The Official Guide To Gunmarks Third Addition by Robert H. Balderson and it is a French Black powder proof Mark, the letters are the initials of the person conducting the proof but it does not say who that was. Some of the same crown with only one letter below indicate the proof house or armory/arsenal.

Much thanks for your input Bpd303 !
I'm inclined to agree with you, the workmanship & tapered top flat that runs full length along top
of the barrel is similar to other French pistols I've owned.
