Help Identifying a pair of Campbell Hausfeld Staple Guns

[dkerfoot]

Can anyone identify this pair of "staple guns?"

Seems odd to me to have a pair in one case and then have them just do staples. They are all black, rather than the more common blue color.

The auction is close enough to drive when I find a great deal, but to far away to go there to inspect them ahead of time.

Thanks!

Just guessing but I think one is 1/4" crown staples and the other is 18 ga brads. When the 'less expensive' guns first came out you had to buy separate guns since they didn't make single gun that would handle both.
