Nice finish. Obviously still several details to be added, but I just want to comment on two things that struck me initially:
Number and placement of the topside joining screws (ref attached photos of the G7es(TV) on display in U-505), and the "Salamander" coil for the warhead igniter (ref detail from a german drawing showing a vertical cut: For measuring-reference: The steel in the hull of the gyroscope compartment is 3 mm thick).
