Unique petcock from SC#81

[acruz]

Here are a few pics of the petcock from SC#81.  I wanted to ask the group if anyone has seen this type of petcock.  It is very similar to the short neck on my SC#1138.  The only other petcock similar to this one was the petcock on the blue/green prototype.  Thoughts?

This is the same petcock that came with Sandcast #410. I originally thought it was replacement, but I am starting to think it is correct.

It's not correct Sam. Belongs to a CL77

Ah, gotcha. Thanks Kp!
