Winter time model building thread.

To be honest I'm not sure what company made this model. It looks like it might be a promo model as the chassis is held on by 2 screws. I do know it is a vintage model based on the lack of detail, chassis screws and 1971 stamped on the rear licence plate. I bought this from a friend who wheels & deals models and when I got it the model was very ruff. I bought an AMT '70 Challenger just to use for parts to rebuild the '71. The windows, engine, spoiler plus a few other misc parts are from the '70 as these part were missing/damaged from the original model. I do not know where to get one of these other than e-bay. I pulled the chassis off tonight to check for marking's to indicate manufacturer but found nothing on it anywhere so all I can say is good luck on finding one of these.
I think it might be an MPC promo.
