| Molly,
That's a good question. Holton made several horns that looked very much alike and all had MF and the emblem on the bell. For example, I bought an MF Admiral for my daughter a couple years ago that looks much like the one on ebay. Its the lower end model, medium bore with normal spit valves. Its a great horn for her, but is not the same as the top of the line "MF", large bore pro horns.
I'd suggest more research for sure...
