Overland Models 1883 & 1885 Alco FA-1 & FA-2 diesels. Both are new in the boxes but show some signs of light tarnish as if they sat out on display for a while. The A unit runs well but the B unit has some hesitation. Could be they just need a good lube. Both come with extra parts packages. The B unit box and foam is in good condition but the A unit box appears to have been wet at one time. The foam however is in good condition. Selling as a set so wont break up. Asking $ 400 for the set
