Im building the railings from scratch.
Similar to conning tower railings- the kit parts are slightly too thick.
In order to make good, solid railings i purchesed 4 spools of copper wire from Maplin
Better than skinning old wires. ;-)
Im using 0,45mm copper wire, Dremel soldering torch, and Koki paste.
Brackets for rope from brass sheet.
Front part of the railing.
It differs from revell one slightly. Some bars are absent on the pictures of U-552.
