No - Definatly a B...Print is clear, just old. Sorry about the text
look of it, but I tried (lol) the bottom is supposed to be an arrow
head, not a corner it's pointing to. It's supposed to be one straight
unbroken line with a kind of "w" in the line and it actually points to 3
surfaces and a bore. Interestingly, the mating part has the same symbol
on the mating surfaces and features. Customer is still looking into it
and will post the reply when I find out.

Thanks.

If these mating parts/surfaces are hand-fitted for final
assembly, then it is probably a "get it this close" to the
final dimension--and that leaves enough material to be
ground off a round surface or manually honed out of the hole
diameter to fit. Think crankshaft and bearing.... Turn the
OD of the crank surfaces to within (say) .015" and then use
the crank grinder to get to the final dimension. Then
machine the bearings (or whatever) to 015" undersize--and
then manually bore and fit the final crank dimensions once
it is in hand. This would be especially true if the
centerlines of those surfaces were required to be straight
line.

Probably "Break edges" .015 (chamfer).
Anything in the change or general notes?

Just FYI - I got confirmation back from the customer today....They had
been looking at it, checking archives ect. and finally came up with....

<drum-roll>

"We have no freakin' idea what the hell that is!" LOL and the solution
was to give us a waiver saying to ignore that callout...

There is always a first for everything.... lol
