Though an F-unit is a very common and typical loco to find in anyone's product line, the Pemco model does sport unique attributes. While Pemco's F40PH appears to be cloned from Life-Like's model and the Roco-produced Atlas SD35 looks to have been the donor for the Pemco model's design, the F9 is unique tool & die work. If there is an inspriation for Pemco's F9, it appears to the Roco-produced Atlas FP7 model from 1976. Look at the nose and pilot, the steps and cast-on handrails, as well as numberboards. Though all could be simply chance resemblence, this F9A does seem to favor the design style found on the previously mentioned FP7 model. The Pemco F9A has never resurfaced from any other manufacturer and has not been knocked-off by anyone else. As with the other Pemco diesels, Pemco reporting marks on the bottom include the company name, model type and stock number, and country of origin
