K Frame Barrel Thread Dimensions

[keithherrington]

What are the barrel thread dimensions on a post war K frame barrel?

These are for all S&W frames.

J Frame, .500"-36 threads. K Frame, .540"-36 threads.
L Frame, .562"-36 thread, N Frame, .670"-36 thread

Many thanks. Been trying to get a Smolt project going and now I understand the problem. Looks like the K frame is the only option.
