Schindler MTA Button Boards

Does anyone have a part # for these Schindler Button Boards? This is an MPH II controller and they look like a typical MTA style Schindler button but the "1 switch" and "2 switch" boards that Adams & SEES offer are not right. They are smaller than these and do not fit. Has anyone seen these before? Are they obsolete so I need to replace the whole housing to fit the newer style MTA boards?

I've never seen those that screw on. All the ones I've seen clip in the button housing.

I think its a type MT not MTA.
