Turntables

Hey , chaps , help !!
Sorting through things today --as you do-- finding things I’d forgot I had–like you do-- and there was this turntable , in kit form , made by — ah!
I had reboxed it because the box got wet . Don’t ask .
This turntable uses the chassis of a loco as the rotating frame of the table . In the absence of any data to confirm or deny this , can anyone tell me if and where such a thing was used ? The T/T is On30 , about 16inch dia , complete with pit , gearbox and all the gubbins except a motor .
I am reluctant to make it in its provided form because , frankly , it just does not look right .
Any suggestions gratefully received , except the physically impossible ones .
Mike
