the demensions you sent me 1.75 x 1.5 convert very closely to the 45mmx37mm that Im sure is the same??
Unless yours is opposite measurements switching width and length?
I sent you a PM. That should be the right one.
Id measure yours in MM and go by that and flat ask the seller.
Only way I can think to do it if not the same as the Olympus ones currently made.
Hope I didnt confuse things.
