Does anyone know for sure, or can anyone suggest another as the true 'first' in this caliber?

I've raised this as a separate thread following a little bit of a quest on the history of the caliber across both GENERAL and COLLECTABLES. Mainly because this is something so generic to what we shoot - and i really can't find the answer.

If you want to check out the previous posts on these, the topics were as follows:

Under GENERAL:
http://www.airgunbbs.com/showthread....is-the-history
To identify HOW and WHEN the calibre of .22 (and .177) came from. The end point we've reached is c. 1845 via FLOBERT and the first example of rimfire cartridges. But you'll see the debate has followed quite a varied course.

Under COLLECTABLES:
http://www.airgunbbs.com/showthread....e-from-and-Why
To identify who 'invented' and/or produced the first example of a .22 airgun. And after much debate covering patents and dates of when different models were commercially available for Quackenbush, Haviland and Gunn, and Hawley (amongst others)...
...the winner at the moment appears to be HAWLEY.

So - the question is:
Is Hawleys's Kalamazoo the FIRST example of a .22 airgun?

I found on garvin's gallery the following:
http://forum.vintageairgunsgallery.c...r-rifle-boxed/
It is described as America's first commercial pneumatic pistol. Available from 1870 (so before the Quackenbush 1871 patent), and the first PIC (all of which are just glorious by the way) shows gun and ammunition - the latter presumably made specifically for the Kalamazoo.

But when i read all the way through, the only caliber i can see mentioned in this instance is .25.
NOT .22.

.....aaaargh.....

Does anyone know if the Kalamzoo was available in .22?
If NOT, WHAT was the first airgun made for .22?
