Attached you will find two screenshots of the Conger 3DCAD computer-model. It's basically part of the carrier, with the most significant Conger parts all drawn in the actual size, using Solidworks, which I basically use dayly at the Design office.

Initially Nigel Watson provided us with the "provisional working instructions" of the Conger, along with two of the illustrations that came with them. At a later moment Nigel was able to find the other illustrations as well. Some illustrations were 2D scale drawings which could be used directly to manufacture missing parts, while other drawings were pretty basic views, which were not to scale. We had a side and a top view of the Conger showing the armoured "dog-house", but no rear or front view, so we weren't able to determine the correct angle of the plates.

This is where the original period pictures came in, along with a number of pictures of the Overloon carrier, when it still had the superstructure. The CAD-model was built up using measurements of the carrier and the remaining Conger features. Combined with the measurements from Nigel's info, this gave us a good start. To determine the correct angle of the dog-house and the position of bolts etc. I placed screenshots of the CAD model onto original pictures in Photoshop. This enabled us to determine the missing measurements and also ensured the bolts and other fasteners were in the correct position.
The last two pictures give an idea what this looks like.
