Does anybody know what I call the backplate of this handle and more importantly where I might find five more of them? It's not the greatest photo but hopefully you can make out that the 'rose' is cam shaped and has a built in latch. This fits on a 3" flat pattern mortice latch with a built in lock. The lock is 1.5" from the spindle - centre to centre. Any help gratefully received thanks
Even my crystal ball has it's limits, a Turn And Release catch by who I don't know,so many styles out there & many makers, & backplate is a backplate & yours is grubby. Take it off, might be a maker's name, patten number, etc on reverse.
