6 & Under (Queen City Adj., Ridgid Pipe, and Unknown auto specialty wrench)

[lauver]

Gang,

I need a little help estimating the likely date ranges of these adjustable wrenches and the brand/manufacturer/purpose of the auto specialty wrench.

Here's the information found on the wrenches:

1) 6 in. Queen City, Bergman Tool Mfg. Co., Buffalo New York, USA.  (OAL 6-1/4", bare steel & black paint)

2) RIDGID Heavy Duty E6, Ridge Tool Co., Elyria O. USA. (OAL 5-3/8", bare steel & orange-red paint)

3) None. (OAL 5-7/8",  7/8" x 1-3/8", stamped not forged, bare steel and bluing)

Here's a group shot:



Any help appreciated...
