A collection of French pocket pistols

[urbanspaceman]

Hello French pistol lovers.
Now that I have your attention, I have a question for you:
does anyone have information about Jean Challeir maker of this hunting pistol (see attached).
I know he/they made arms for aristocrats Count de Clermont, Duke de Bourbon and Prince de Conde; and also that he was made a master in 1758 and operated from Rue Dauphine.
I never see French pistols for sale or auction here in the UK and I've seen no information about Challier other than what I have detailed.
The pistol is in perfect condition and perfect working order; it has a 22cm long barrel with a 15cm(approx.) bore.

Thankfully we now have some very impressive pictures of some very impressive pistols.
I particularly like box-lock actions as well as Queen Anne barrels, and here we have both. Thank-you folks, it is much appreciated.

Thank-you. I don't speak French so here is what Google makes of the less obvious or previously established bits.
Inventor of a new way of placing the plate of a rifle which makes it capable of being removed and put back in place in an instant. Approved by the academy 1772 and 1774.
He demonstrates that short rifles carry an equal load, further than long ones and is obliged to collect the lead from those which are separated by an operation simple which is particular to it.
Anyone make any sense of it?

Danke Corrado.
Ich spreche auch nicht viel Deutsch.
Schade, denn ich mag sowohl Deutsche als auch Franzosen sehr.

My five cents:

Inventor of a new method of attaching the lock to a rifle so that it can be removed and reinserted in an instant.
He shows that short rifles carry farther with the same load than long rifles, and undertakes to collect the lead of those that deviate by a simple operation peculiar to himself.

I know we are deviating from the initial theme of this thread but does anyone conversant with ballistics comprehend his declaration and agree or disagree with it?
I assume this concerns long guns rather than pistols, which seems appropriate given his connection to hunting - but I may be wrong.
The original owner described the pistol as Venerie Louvetier which is apparently wolf-hunting on horseback, run by the Grand Veneur ie Master of the Hunt and Royal Game Warden.
