Would a Monarch 612 steady rest fit other Monarch models ?

Including those of less swing ? (by not using the riser plate) This one is for a 1968 vintage 612 that is 20" swing.

From the original machining I'd guess it was for a larger bed but less swing Monarch - simply because the original base is "wider" (center of vee to center of flat way) than the adapting piece.

See what center height is without adapter - my 16 / 18 1/2" actual CW16 is exactly 9" to center line of spindle from flat way

The rest of the original unit looks like mine

CW16 is 8 1/2" C/L vee way to C/L of flat way
 
Maybe, someone has made a adptr to fit a larger lathe already...Phil
I was sort of assuming that Monarch made the adapter block so as not to have a gazillion different steady rest castings for their amazingly varied lathe models. OTOH, now that you mention it.... if it was Monarch standard issue there probably would be some paint on the block...so perhaps it was a shop adaption sure enough...fits the 612 perfectly though...
 
If with the adapter off it measures 9" tall to center from flat way and the flat way center to vee way center is 8 1/2", it likely was made for the CW / CY 16" lathes
