Incorrect. MTH doesn’t have the RS-3 molds, as others have explained above. As for the SD40-2 Weaver molds, MTH started using those about 20 years ago while Weaver was still in business, as they also did for the Alco C-630. MTH did not acquire any of the Weaver line after Weaver went out of business.
