Hi all:
I picked up what I believe to be a Max Gray SP AC-11 back in about 1991 and would like to determine it's approximate age and value. I suspect that some GI may have bought it in Japan or Korea.
The model is mostly brass but the frames, top of the tender and a few other items are copper in color. When I got it the brass was tarnished nearly to black but I clear coated it after the cleanup job back then and still looks real good. It has been sitting in a closed display case ever since then. I don't know what alloy that brass is but it will show noticeable discoloration from tarnish within about 10 minutes of being cleaned hence the clear coat. The only physical damage was some broken solder joints on the boiler walkways and the tender weight was no longer attached and was rattling around inside.
I replaced the original solid pieces of brass that represented various appliances on the boiler with castings from Precision Scale and added some plumbing and valve gear parts as well as handrails on the deck between the Locomotive and Tender. Since the available numbers at the time were AC-12 I renumbered it to 4275. I do not recall what the AC-11 series number was. I left in the original motor brush springs that appear to be made from rubber bands in place and back then I did run it as much as I could on a my 36" section of track (about 3" each way).
I think I still have all of the original non realistic appliances that were once on the boiler as well as the original numbers.
Any info that anyone can provide will be greatly appreciated.
