Thank you Alex, this has been a fun little project. I didn't actually get involved when quad bridge was spliced. I just looked at it, said to myself, "I can do this", and winged it.
Thank s Jesse, those are some deep thoughts regarding the hobby, and I wholeheartedly agree. The 450 may very well be the most common accessory ever produced, thanks to MPC, LTI, Lionel LLC, and I think even MTH. Even though I have gotten over much of the sentimentality over postwar, I would never do this to anything with collector value, either. There are always listings on eBay for these. I've been following a bunch for the last couple weeks, and sale prices have ranged from just under $20 to around $35 depending on condition. There's one crazy auction, for a lot of 3 nice moderns, at $155. Not sure what those guys are thinking.
