I have recently converted the mechanism from a canopy blind box into a mechanism to fit the rear offside blind number display for RM13.
I had some 2mm Zintec laser cut to form the frame, which I then had powder coated. I then used an old canopy mechanism. I had to alter the handle, and swap some internals around, otherwise no problem.
These were fitted on all RM's up RM1742. I have made 10 frames in total, so I have some spare which are availible, not sure of the price yet, but should be ok, if anyone is interested, all they will need is an old canopy mechanism to convert.

I used a modified DMS side display to make up an offside box for 531. However this looks much better! Let me know the price when you are ready.

Put me down for one as well - I'm also using a modified mechanism from a DMS side box and it's not completely satisfactory!
