Hi, I purchase 3 Mantua locos on eBay and condition was not working for parts, I disassemble all and was able to build 2 locos, one as DCC with sound and is running great and mechanically is 100% and second was DC only and is sold. Original DCC decoder was not existing so I replaced with premium sound decoder with sound, Bowser dual cube speaker installed, all lights are LEDs, fire box flickering LED installed and red in tender, and little decoration. I'm offering free repair, bayer is responsible for shipping in and out. Please ask questions, and make offers. Thank you for viewing.
