None the less, if it is French thread(and I think it is), I will install it and put the Suntour Perfect on the shelf, for the time being.
So far, the only original item missing is a proper front derailleur and, believe it or not, I did have one that I gave away a few years back when I had to make storage room(gave a box full of Simplex stuff away, at that time). Not sure, but I think that this is the front derailleur I should be looking for(picture is from Velobase)...

My '72 PX-10 had the original Delrin FD. There are some pictures halfway through the first page of it before I replaced it.
