I like your photo very much! I had the chance to visit Hanhart in Guetenbach. I met some of the guys who made the re-edition possible. I think that they did a very good job and the re-edition is very close to original.
There are some differences like the bicompax. Due to the layout of the 7750 the compax are more close to the center in comparison to Cal. 40/41. There has never been a "15" or "45" on the minutes on the outside of the dial. The lugs are more strong because it was cut out from one stainless steel piece. The lugs of the plated original are soldered. And of course or pity the 7760 has no flyback.
The 417ES is the best Vintage Hanhart for wearing, because of the better material like steel case and post-war movement.
My re-edition is worn a lot more than this old brother from 1943;)
