Yes,these look great. They are a Protocraft type coupler,though not produced by Protocraft. There's a single lower shelf,a double shelf for tankers and an H tightlock for passenger cars. According to the photos,they've been produced but not cleared for release to us modelers yet. I don't know why someone hasn't at least announced that the project is in the works even if not ready for sale.
Did you see the new Prototype model of a Racor operating groundthrow switchstand? This model is a "first" in any scale. New Century throws are on the way. The Racor model is ready for sale and are $24.95. I think the link here,is firstname.lastname@example.org. It's 3:39am so if that link doesn't go through,let me know and i will look it up again.
Thanks for the interest Mike,hope others will show interest,also.
