There are one or two around the world that I know of who are making them and I am certainly not the best. The best, in my opinion, is Donald McNarry (UK), but he is now in either his 80s or 90s. Two of his miniatures. ALABAMA and KEARSARGE were offered for sale at a London auctioneers earlier this year for £26,000 to £28,000 each. They didn't sell, but that was probably due to the present state of world finances. Lloyd McCaffery (USA) is another, but he never does steamships, only sail. One of his models (3 1/2 inches long, once sold for $100,000!) There are a couple of others in the UK, but don't tend to see them on forums.
I am extremly lucky to get a few hundred for mine. I suppose I lose out because I only build what I like and that excludes all the well-known subjects. It would just be nice to have someone that I could exchange techniques and views with on the subject of miniature scratchbuilt, but I am not in contact with any of them.
