That's some pretty cool stuff, right there. Apart from just ogling the prices (.45 ACP for $2.46 per fifty rounds?), There's some neat stuff in the ad copy.

It's also just plain cool to see what was popular enough to go into a general-interest catalog back then. Most revolver cartridges are offered in black powder or smokeless. There's a ".22 special", which I'd never heard of before today. There's .30 Luger, for your Great War trophy, I guess. And of course, .38 ACP matter-of-factly offered between the .32 and .380 ACPs. Glorious.
