Hi Si and all,

Here are some photos of the 1/2 sized ones in use at my local 2'gauge museum.
It took some time to find where I'd stashed these photos and then get them uploaded.
I knew I had them on my hard drive somewhere.....

First up one of the couplers out in the open with the pin down and the jaw locked.

And another photo of the front end of a different locomotive.
The original low-height sugar cane loop coupling can be seen under the buffing block below the knuckle coupler.

The coupling here has been swung out of the way,
to allow another coupling on another vehicle to push past it,
and minimise the space taken up in the shed.

Two of them on different locomotives with the pins up.
This allows the jaw on each coupling to move and the couplings to separate.

The supporting bracket under the right-hand coupling,
prevents the weight of the coupler from causing the coupler to droop.

This might be an idea, for those who model with long-shank Kadee's or similar.

And to close out, a fixed jaw shunting coupler and with a knuckle coupler.

With this arrangement, you lift the pin on the knuckle coupler,
as you shunt up the movable jaw fits into the slot on the fixed jaw, as you close up, the jaw closes,
and then when you bump up, the pin drops and the jaw locks,

In model terms, in the larger 1/43 scale and using 16.5mm tracks for 2' gauge,
the standard #5 coupler head is close to scale. and the actual lower height of the coupler,
works out at very close to the standard HO coupler height again in the larger scale.

To close out, some photos the knuckle couplers of one of my 1/43rd scale models,
and the prototype car.

And the prototype..

See, just like a #5 from a distance.  :bg:

That ought to do for an introduction to 1/2-sized standard knuckle couplers.
