[Matchlock]

The flask attached first is the one that is closest to mine; its whereabouts seem to be unknown. The scan is taken from one of the many coffee table books that sadly do not care to give references.

Attached next is the finest known sample from the series, etched all over, preserved in the Odescalchi Collection, Rome, but both the wheel spanner and screwdriver are missing.

The following is said to be in a French private collection, the turn-lever spring of different construction.

Next is a specimen in the Musée de l'Armée Brussels, showing the hinged top mount open, the screwdriver missing.

Follows a plain sample in the Wallace Collection, London, the cut-off and screwdriver both missing.

Finally attached are two plain samples from international auctions.

These are all I have ever come across in more than 30 years of studying.

Best,
Michael
