I have:
3717 Fliegerchronograph with gen dial, gen hands, gen crown, gen tube and Swiss 7750 with German day wheel. This one I may send to Avit for DLC treatment.
3253 Mark XV with gen dial, gen hands, gen crown, gen tube and Swiss 2892. I'm using the case from the XV Spitfire since it has the correct lug width (19mm) and caseback engravings.
Hopefully I'll assemble these soon. I've had the parts since July!
