Yeah these are non-upgraded models from Walthers. Should never have been in the "Master" line and certainly not similarly priced as BLMA models
Did they at least leave the coil shields removable? One of the craziest issues with the Walthers cars was that they had full interiors, then proceeded to GLUE the shields in place.
I think atlas could salvage the car by: thinning down the steps like Walthers did on their retooled GSC flats, new or retooled shields that have a lower profile and handrails, replace the plastic walkway with an etched one, adding body mount couplers and metal wheels. But after all that, what is left of the original model?
