Besides measuring the barrel rib a quick and easy way to tell a post war narrow rib K-22 from the wider rib (weight matched) version that supplanted it is by looking at the top strap where the frame meets the barrel,

Narrow rib frames are notched at the front of the topstrap to mate with the narrow rib barrel (center in pic ),

The frame on the wider rib gun has no notch cuts so it will mate to the wider rib barrel ( Right ) Notice the top strap is also bead blasted to reduce glare.

The one at far left is a pre war K-22 with no barrel rib.



Ralph once upon a time I was head over heels collecting K-22 variations although the one that managed to evade me was a post war narrow rib in "Bright Blue",
Sounds like you may have had a very very rare anomoly there with a wide rib five screw K-22 in "Satin blue" as I do not recall ever seeing another like it.

BTW IIRC the 5 screw wide rib K-22 may have had one of the shortest runs for post war 5 screw K-22's not including anomalies like nickel or LERK.

PS looks like Photobucket pics work again ?
