holding back on all the coupler conversions I had planned for mid year awaiting the production of these ProtoMates. I am fairly convinced these will be the best option; even compared to those by the fellow at bowser whose product raised my expectations. keep us posted David! sincerely, Gary
There is still a lot of time before 2014 is over but how are these couplers going, any updates? I've also been holding off on a few coupler conversions that might require a bit of cutting and chopping to fit MTLs.
