As you might expect, most of my Channel Locks predate the Blue handles.
Most of the Arc joint CL's; the second from the top are unusual, they are No. 415. anyone tell what is different? This is the only pair I've seen. The blue on the grips of the bottom pair are not factory, I dipped that about 30 years ago.
The "other" Channel locks; lineman's and their version of "vice grip" now discontinued. I like these add would by a second pair if reasonable and not buggered up. The blue handle got broke by being dropped, and I glued the large chip back in, then wrapped the break with 30 ga. steel wire, and painted it over with nail polish. it just got the old wire re-wrapped and a new coat of nail polish. (Lasted about 20-25 years...).
This was going to be a pic of "Not CL" but I found on another thread tonight the one pair of "No Name" were in fact CL. (Pic was take a couple of days ago). From the top: CL GL-10, another pair of "no name", Diamalloy, and Proto's with the slip joint style of pivot.
Lastly, the CL lineman's (Middle) compared to other makes: Crescent to the left, and Pexto to the 2nd left, Krauter's to the right, and R. Pennings (Fennings? first letter is pretty obliterated...) to it's right.
