Hi all. I know from reading a lot on here, that the smaller guage trains are the most popular, so I hope someone might know about my questions on a Lionel. I have a whistling tender that is plastic like the one I had on mine as a kid. Mine, though, was somewhat newer than this prewar Lionel 225E. On Ebay, I saw a 225E for sale and the guy claimed that the prewar metal tender was part of that train. My plastic whistler looks more like it fits. The metal whistler (didn't know they made whistlers that far back) looks too small for the engine. Which is correct? I hope the plastic one I have. Other question is, can I convert this engine to a smoker? Front opens up like the smokers, but it has no element in there. I used to repair tvs many years back, so I know how to solder okay. Thanks in advance for any help you can give. All have a nice day. Jack.
