On another thread there is an interesting discussion about getting the right connectors and parts to make repairs, etc. It can be a pain at times.
I wondered if anyone else has every done this: Cannibalize a "perfectly good" (runs well, undamaged, all the parts are there) loco to get parts you wanted to repair another?
I did this several years ago, when I had a worn/broken tether on a PS1 scale ATSF 2900 that is quite important to me (I consider the 2900 series Northerns to be the steam locomotive of all time and this PS1 model is still the only scale 2900 I have). I had another PS1 steamer, I can't remember what now (which tells you where it sat in my list of priorities) but it was smaller - I think it was a Hudson. I had bought it used at a swap meet. However, it ran and was undamaged, but had a tether and connectors that looked brand new and would fit perfectly. Yes, I could have reserached the part number, maybe found a source, ordered, waited, etc. but a perfectly good repair tether was right there . . . So. . . I took the tether and the rest of the loco went in the parts bin . . .
I still run the Northern occasionally. Its old and close to obsolete with respect to sound (rather basic) and attached details (some of the attached parts are clearly unpainted plastic, etc.) when compared my glorious new 3759 Legacy, but its a 2900 series - bigger, grander, and nobler - so I've never regreted sacrificing that - whatever it was.
