On Trap grades, the left lock shows 5 men standing in line at the trap, the right lock shows a hunter with a quail flushing.
The wood on a Trap grade was decent and like you said yours is a re-stock from Fajen and they put on what the customer paid for.

I'll have to wait for your pictures, as the ones on the L.C. Smith site were small and I don't know what happened on the picture showing the left lock plate.
