Hoping for a little help identifying these lever caps. I am used to seeing lever caps from the typical Stanley bench planes from late 1800 to late 30s. These caps I have attached have me baffled. The one on the left looks pretty good until you turn it over. It is missing the typical flat metal shield which allows the lever to just flop around loosely. The second from the right looks pretty normal but it has a rough surface like it was cast in a rougher state. It may have been painted black like the one to its right. It also has the same rough surface and some black paint present. The one on the far right looks like a cap iron from a Stanley #9… the so called long neck lever cap, but is has a hollow back not solid which I have seen. Is this a long neck lever cap for a #9 but a different “Type”. It is 2” wide and 4.5 long less the lever, 2 -1/8” from the top of the keyhole to the top of the body. Any help identifying the planes these were made for would be appreciated.
Thanks
Mark
