Manton Target Pistol

[sabertasche]

Hi all, I recently did a big trade with an advanced collector and part of the trade was a single target or dueling pistol by Manton. I understand that Manton is a premiere maker but that's all I know. Which Manton is this? I have not taken this pistol apart as I feel if anything is to be done it must be done by a professional. The barrel is not rifled, calibre is 1.4 cm. and there is no rear sight. I have no plans to fire it, just enjoy it as a fine pistol.
