And photos. Note the interface of castings on the Wolfer part. Also note that the wheelbase and overall lengths are identical, although the Wolfer casting seems beefier. The interior space is identical, which says to me that one can simply put Wolfer trucks under a JLC GG1 and be done with it. The reduced flexibility will be negligible, I think, but at least you would have a display model.
I am trying not to repeat myself - Bob's idea is to split the casting down the middle, cast the brass in two parts, and then solder and paint(!). He would need to do one set to really nail down the price. My thought is that the Wolfer sides could be mated to the Lionel ends - I think I am repeating myself - to reduce initial mold costs.
