I finally acquired a Dorfan 610 derrick. I'll post pictures when I get it and finish cleaning it up. Looks like there is lots of caked on dust and grime to remove but otherwise in good shape. Question, was this derrick car ever made with a maroon roof? All I see in online photos is a roof in a shade of green. I'm wondering if mine was repainted?
Also, is this the Greenberg book on Dorfan?
