Now you are talking, the M-2206 is my pick of the litter because of its weight and less felt recoil, mostly all stainless construction. The Sight Adjustment Tools you pictuered and the cleaning rods were included with new handguns by the factory, I won't attempt to date them but have seen a photograph including all examples and the era in which they appeared.
Will also mention the M-2213 & 2214 which are pocket size pistols. Ventilated Rib versions of the M-422, 622 & 2206, examples of which I have not seen in person, are encountered less often and bring premium prices. Thank you for clearing up my missunderstanding of your original purchase, again, enjoy your M-2206!

One other bit of information I failed to mention is that the M-41 Magazines also fit these pistols.
