Protocraft has introduced a new version of their Type-E coupler. The coupler represents all-new tooling that improves the operation. The shank has been changed to fit a new draft gear design. The new shank has a .040″ greater spacing from the back of the head to the slot. The picture below shows the different shanks. The new coupler is on the left.
The draft gear changes are significant. The old coupler design will not fit in the new draft gear. There is different striker on the box. It is attached to cover plate. Protocraft used the Gould design for the new design.
Rather than repeat information researched by Protocraft, I have scanned the instruction and inserted herein.
I have found the new coupler is easy to install on freight cars. I did add a coupler to a Glacier Park Models tender. The picture below shows has nicely the draft gear fit on the underframe of an Intermountain 1937 boxcar. This is a huge improvement over the typical draft gear found on Kadee couplers. You can now build a scale underframe including the draft gear.
Here is an example of the new draft gear fitted to the Glacier Park Vanderbilt tender. The new top operate is right choice for a tender.
The above shot was taken by Rick Leach many years ago. The NP repurposed tender bodies into water tanks. It would create a small tank that would work for their lighter power like 4-6-0s and 0-6-0s. I don’t remember where Rick took this shot but was likely on the Tacoma Division. It would make a neat model.
Hopefully, this posting will shed some light on the latest Protocraft coupler release.
