Ray, your model of the Oldenburg reminds me of something I started many years ago and was wondering if you would be interested.
When I was working in the Meyer Werft shipyard in Papenburg in 2010 I was having a walk around the offices one day and came across this beautiful builder's model in a glass case. Having had a chat with one of the guys in the office I mentioned I enjoyed ship models and he dug out some drawings for me. I thought one day a model plan could be drawn up from the drawings and the collection of photographs I took. Then never got around to it and probably realised it was out of my comfort zone anyway!
I have absolutely no idea where the plans are now however, if you would be interested in either making up a set of model plans or building a model yourself I would be happy to have a good dig around and see if I can locate them.
It would be very rewarding to see something useful done with them rather than they simply sit in the bottom of a box or drawer until somebody sticks them in a skip when I have gone!
