Anyone have any similar, or seen the "0" after the model number?  Trying to figure out what they mean.  These are quite early wrenches and the model nomenclature style "B-###" predates any of the catalogs available ('52 is earliest I believe).

Those B-NNN part #s are in the 1949 catalog but changed to the newer ones by 1951. Haven't seen the extra "0" before so might not even be factory. Maybe an owners mark or something??

I have a number of Mac wrenches with the 0 marking.

Mike, I'm sure I'm not alone when I say I'd love to see pics of those!  Thanks for chiming in!

Here's a couple I grabbed.
B 101 0 is a 13/16 x 1" offset DBE  [like yours, Todd]
B 99 0 is a 3/4 x 7/8 offset DBE

Well, I think we can definitively rule out those being owners marks.  Now, what are they?  A one year only date code marking experiment for 1950? (really doubt they are '40 models)

Matt,
Does the '49 catalog have normal offset DBEs?  Also, any possibility we can get a scan of the '49 catalog?

Another oddball.  First MAC wrench I've seen without a model number.

Never seen one either.  Isn't that a pretty short wrench for the size openings it has?  Though it isn't marked as such, could it be a 'special'?

Mark says they made short and long pattern DOEs and didn't find the length strange.  I was with you on the length....

it's not listed in any of my early catalogs so I agree it must be a special application. a 3/4-7/8 standard wrench is 10 1/2" long.

So short for such a LARGE 13/16" nut/bolt. Must be for something that does NOT need to be really tightly secured!
