    We made these at the foundry when working to cast a new front number plate for the restoration of "The Texas" locomotive.(https://en.m.wikipedia.org/wiki/The_Texas_(locomotive)). These are sand cast brass mis-runs - the pattern was too thin, so the metal cooled before filling out the whole part. The picture at the Wikipedia link shows the actual complete medallion we made, finished and installed on the train

    More discussion about these is here -> https://www.carolinafirearmsforum.c...otive-medallion-mis-runs-sell-or-scrap.19638/

    The 2 medallions in this thread are $200 each. About 16-3/4 inch diameter. I'll post pics and description of each one below. I have two other Mia-run medallions that are not as filled out, so are are cheaper, posted here: https://www.carolinafirearmsforum.c...m-locomotive-number-medallion-mis-runs.19762/

    These are not perfect - they are sand cast, and were cast from a reproduction number plate that was made for the locomotive in the early 1980s, that was also sand cast. Because the metal didn't fill out, there are sink areas on both of these where the metal contracted as it cooled. We had added 1/8 inch thickness to the back of these, but it was still not sick enough to get them to run

    They are sold as is. I have wire-brushed the front to remove surface discoloration from the heat of the metal and the oil in the sand mold. You can see the difference in color on the back, which I did not brush. The back side still has the "leads" attached which is what the metal flows through to reach the part. The center is a large nut that was how the plate attached to the locomotive - it would have been drilled and tapped if this casting had worked.

    Pick up at the foundry in Kernersville area, RTP/Cary area, or places in between as I drive. Also driving from Apex to Boone/Linville (and probably Asheville) right after Christmas

    Medallion A - $200. Weighs 22 pounds. This one is the closest to complete of the four mis-runs.

    Medallion B - $200. Weighs 28 pounds. I think this one would look really cool if you trimmed out the middle in between the spokes, leaving the number 12 with the spokes behind it. You can see the different textures of metal on the front of this one - where the metal is smooth, that's where it was really cool. The hotter metal is rougher. Seeing that this one didn't work, and the hot and cold gradients, Even though we had the huge leads on the back of it, we realized there was no way to cast this without adding even more thickness to the back, which is what we did next to get next a complete one to run. The piece you see cut off the back was a riser we put in the back of it, hoping that letting the gas out the center of it would help the remainder fill out

    Both of these medallions are still available. I cleaned the sand off the back of them today and hit the cut edges on the back with a flap disc so they aren't so sharp. Will be traveling to Boone, Linville, and probably Asheville December 26-28 if anybody along the way or up in that area wants to check them out

    I am traveling in to Black Mountain on Sep 17-ish, and could bring along if that helps with delivery
