Hi all,
I have several Olympia SMs, and would like to change out the much more supple platen from my 1977 SM9 for the rock hard one on my 1956 SM4. I do not think I can do this, because the variable release on the 1956 is via a button pressed IN on the right platen knob, and the later one via pulling OUT the left platen knob. So I assume different mechanisms=not interchangeable platens. But since both are working inside the platen in the same direction (to the left), I wonder if maybe I am wrong. Anyone got any thoughts before I try it and probably come to grief? Thanks!
