i have reciently acquired a non-powered “b” unit grand trunk western. it is about 1.18 lbs and the shell and base are lead? the local train shop said it is 10-20 years old.there is no name stamped inside or out.One suggestion was that it was built by (carry?). it is a well detailed engine and actually weights more than the “a” unit. any comments please forward to rodpayson@shaw.ca thank you very much.
