Flint pistol - Nationality?

[Pukka Bundook]

I agree with Corrado that the pistol in the opening post appears to have an Italian fluted barrel. This does not mean the pistol Is Italian, as this type of barrel was used over Europe and the UK.

In Corrado's post above, he shows a pistol with a turn-off barrel. This is a very different thing, as the barrel was unscrewed for loading. In the pistol in the opening post, the muzzle decoration is just that, decoration.
It is a nice pistol, and I would have Guessed Italian, or Germanic or somewhere between the two!

Very best wishes,
Richard.
Corrado,
I was presuming when I wrote the above, that your pistol used the rifling at the muzzle to take a spanner for turning off the barrel.
Is this so?...Or, is there a lug on the barrel we can not see in the photos, that a wrench fits over? (This would be just in front of the stock towards the breech of the barrel.)
