They were cataloged (set#1575) by Lionel 1957 and 58 a very popular 027 set for Lionel, they also released it as #219 in a uncatalogued set 1959 for Sears. I seem to remember LTI may have released a MP Alco with a nose decal in the 1990's I need to research that.

Thank You Franktrain
Nice picture! I'm out of the country and can't wait to fool around with this one. I've read that they are real pullers. I thought Lionel gave up on the magnatraction before this was made. I have some graduated trestle that I would like to use. I looked at some pictures of the real Locos and like the two tone graphics with the Screaming Eagle design that MP used. This not having a lot of collector value, probably won't make it any less valuable.
