I think I have about 3 but not sure how I came about them all.
I know one is from the victoria where I set the flywheel into the base and made a short pedestal. I also cut my beam engine bed plate down to 1″ and did the same as the victoria but that one is long lost.
One thing I would suggest is ditching the 2BA fixings as they look way too chunky particularly with standard heads. Small hex 3BA or 4BA with standard looks a lot better. Or go metric with small hex in which case M4 and M2.5 to replace the many 7BA
