Haven't seen a Knocabout in a long time!
Neat little piece of 50's design,,everything all assembled and pretty much permanently riveted together betw the two stamped out side plates.
Though you can pry them apart if you need to, nothing much ever goes wrong with them to make you need to do so.
Genuine coil springs inside there.
Original instruction manuals are hard to find,,they were printed on the inside of the lid of the box that the pistol came in.

Nice acquisitions,,of course I'm drawn to the Sheriden oddity.
