The top photograph looks like the action face/breecch end of barrels interface is 'stepped'. Wat i mean is that the metal extens further down the rib extension on the left side than it does on the right. In fact, the left tube seems to come a degee further doen than the reight.

Is this atrick of photography ot is tehre something going on there? Have a close lookand describe what you see.

The gun is in work condition overall and looks to be built on Greener's 1880 'Facile Princeps' action. It is not a high grade gun but nether is it the lowest.

Greener boxlocks can be troublesome of they have been messed around but the quality of manufacture therough all the grades is high.
