My mate mapman57 built this for me, actually a Phong 9401/0 engraved mid case 8 serial 1976,phong bezel assembly,Athaya 702 tube and crown,swiss eta,gen service insert and crystal bought off therolex forum,yuki dial and hands, gen 93150 bracelet with rep 580 end links
Checked my emails and used the 2 704s so the 703 is gen , trying to figure what the others came off, think the Rep was knackered , I'll get another picture to show
I haven't really a clue, will have to go over some old emails as I had a few fitted and everything got mixed uo,as you look at them head on the one with the tube which is the left one in last photo is exactly the same as a 703 vintage I just got from sub007,
Your lucky day,i have a complete 1665 bezel assembly off a mbw snowflake i bought a while back,it was 5512 case with the 1665 fitted,i had to change it to a wso normal one ,send me a pm
