I finished up the grabs and added some scratch built underframe detail. It's done as far as I'm concerned.
I would like to offer it as a kit but there is quite a bit of hand bending and scratch building of parts. I'm not sure it would be for everybody. I need to find a better source for the frame details as I wouldn't expect anybody to whittle them out as I did. The end grabs are modified from a GMM set for the MP Bay Window caboose. At least my Y-3 has something to drag behind it now.
This is great, if there is any way you could consider offering basic parts as a kit I for one would be very interested.
