Our own Vic Venters had, at one point, a sidelock ejector out of Belgium, that was going to be a restock project for himself. His stock dimensions, like many of us, were such that off-the-rack was mostly not possible.
Racking my brain to try to remember the name, but, coming up with nothing.
Perhaps he will chime in with what the outcome is/was.
I do remember he said the quality was top of the line.

Best,
Ted
