1929/1930 gun cat in Montana library
 

Just saw this on worldcat.org. More keeps getting listed online by different places, and more things that were not on online library catalogues continue to be added.

It's listed as 32 pp 1929? but might be 1930.

I don't know their policy about low-res pdf reference copies. It seems to vary considerably across US fr free to a dollar a page or more. Sometimes after 1924 is an issue (a copyright law benchmark of some kind) but also sometimes places raise the date for research purposes and considering trade catalogues are "promotional material".
