There are some slight changes in the K 22 Outdoorsman from a early vs late shipment standpoint. The early guns (as shown above by RK and David) were shipped in the maroon boxes, with call gold bead front sights, and a rear sight with a single elevation screw. The later guns as mine, were shipped in a red picture box, with a call silver bead front sight, and a rear sight with double elevation screws. One other niche for the K 22 OD collector is the subtle difference in the four page brochure. Note the difference in in the trademark at the top left hand corner of the page. I believe the first brochure pictured is the earlier one.
