The initial German A5s had all 6 batch hulls onwards (increased armor) ... welded front deck cover plate.
All the Dutch A5/A6s all were rebuilds with their original hulls .... bolted front deck cover plate with gap.
No manufacturer can get it right ... all want to take shortcuts ...
Hulls from 1st to 5th batch always bolted including exports.
6th batch onwards hulls always welded ... why don't they just offer the two variants to inserts offering the correct recessed/gap possibility with the bolted version. Would make a backdate to earlier batches much easier and the OD paint option possible.
With later German A6s there are suppose to be some bolted variants with additional welding ... but I haven't seen any proof of that yet ... anyone got pics maybe ?
So building a correct Dutch version would dictate reconfiguring the cover plate with a gap (tricky !) and adding the bolts ... plus other changes on the turret amongst other things.
