Jeff, thank you for the response. And to clarify, yes, I am asking about consolidating them onto a double backplate.

: I'm not certain of what you are asking, but let me give it a go
: anyway.

: With either the Monte Carlo or the Master Time, you will need a
: specially-made back-plate to mount the timer to a flat surface.
: There is a bayonet system, etc.

: If you have each of these two timers on its own back-plate, then
: the question is whether you can consolidate them onto a double
: back-plate (with the bayonet system) or whether the two
: individual back-plates for the MC and MT can be mounted on a
: single plastic plate.
