Two wrench questions

[Northwoods]

Came away with two interesting wrenches yesterday.
The first is an older 8 1/2" ===CRAFTSMAN=== double line 11/16" combo.  ===FORGED IN U.S.A.===  The forged in mark is on the back side near the open end.  Very indistinct.  It could be a B, a P, or even an A.  It is that foggy.  Beautiful patina.
Any thoughts on its manufacture date?

The other is an older 5 1/2" open end 1/2" X 9/16".  The identifying marks on the front have been ground off.  But some remains.  9/16 MFD###########1(?)8 U.S.A. 1/2.
The back is blank.
I tried a Google image search and came up with a T5918 TRU-TEST on ebay.  Sorry...the image inserter is not working.
My question: Why might someone have ground off the TRU-TEST logo? 
Was there some legal squabble a la Plumb v. Plomb?
Any thoughts?

"TRU-TEST" really never had any dispute.  Trademarked in the late 20's by Milwaukee T&F, then transferred to Lectrolite when it was formed in '32.  Lectrolite Corp used it up to at least '53 when they partnered with S-K, and possibly beyond.  No controversy that I know of?  Here's some history (half way down page) if you're interested: http://toolarchives.com/node/793
