Hi, may be a bit late.
Yes, the c.74 in a nickeld finish with genava strips exist. I think those
where made probably for the US market.
Here a sample
Sorry for putting my copy right on it; I find too many of my pictures in
fantastic watch web pages.
Kindest regards

P.S. I think in a ref. 325 you can't find them (the c.74), as the nickeld
where produced mainly as early
movements.
P.S. PS.
in the same period also c.73 als nickeled movements with geneva strips were
produced; and there are even earlier movements c.73A nickeled without geneva
strips, just maching signs (to be checked it this are full body "Neusilber"
movements)...
But filally the A-version became the "ordinary" c.73 (from the mecanical
viewpoint but guilded)
