I have guy contact me about this Hamilton movement
not sure if will fit in regular case as some have hi pillars is this the one or it will fit in regular case? it shows as Hamilton 970

I believe that will fit ANY 16s PENDANT SET case from that era but keep in mind the movement you've shown is PENDANT set.

It should fit any standard size 16 case However it is pendant set like Robert mentioned but it is also positive pendant set and takes a special winding stem. The winding stems are not as available as regular winding stems. I had to make my own by turning it down on a lathe. If he has the winding stem that is great all he would have to do is find a case the the pendant height would be the right length for his winding stem. It he does not have the winding stem then he will have to find the proper type of winding stem and the proper pendant height on the case to make it work. Time consuming but should be able to work it out.

so is no buy as he try to unload that one on me

They are beautiful movements but when you buy them in pieces it takes some work to put all the right pieces back together.
