The Liege manufactured Imperial Contract revolvers have serial numbers on almost every part, even the ejector rod! There are actually 17 numbered parts on the Belgian revolvers; the frame, side plate, barrel, cylinder, trigger guard (in two places!), left grip plate, right grip plate, grip insert, ejector rod, ejector rod carrier, trigger, cylinder pawl, cylinder pin, breech block, hammer block, hammer and loading gate.
The serial numbers on the left side of the Liege manufactured revolvers. Visible are the numbers on the ejector rod carrier, master serial number on the frame, the number on the trigger guard and trigger. There is actually another serial number on the right side of the trigger guard.

As with later Russian production revolvers the serial number is found on the front face of the cylinder. However, unlike the Tula produced revolvers there is a Liege proof and inspector’s mark on the back face of the cylinder. Note that there is no equivalent of the OTK mark on the front face of the cylinder.
