What is this tool thread?

I've been following this thread for a while now. At least 50% of the tools posted I've found in my grandpa's garage (he was a Chrysler mechanic in the '50s - '60s). I'm down to just a handful of unknowns so I thought I'd register and post. Pretty much everything in the picture is unknown, except the green checkmarks.

A: has no markings and looks handmade from mild steel but is actually hardened/heat-treated so I'm assuming it's a real tool. Reminds me of a trim tool except it's beefy enough to split a ball joint.

B: stamped "A.C.Co. 2379" with a shield logo (like Vlchek).

C. drum brake tool?

D. says "R. L. Day" and "Pat. applied for" but after hours of searching the gov database I never could find the patent. Reminds me of spark plug boot puller.

E. These are stamped "NAPA" and nothing else.

F. Looks like a brake pad spreader but it's too small/weak for that.
