Snap-on crowfoot wrenches and logo

[danielzig]

So I purchased a set of Snap-on crowfoot flare industrial finish wrenches 1-1/8 to 2-1/4 16 pc set today from a co-worker. I was wondering if anyone has a part number or any info on these wrenches. There is no part number stamped on them and they have the snap-on logo underlined. I was not able to locate them on the snap-on website.

315AN is the chrome version from 1-1/8" to 2".
They are under Wrenches>Crowfoot 1/2" Drive>Deep
The industrial finish is discontinued, as are many other industrial part numbers.

Much appreciated. Do you happen to know when the underlined logo stopped being used?

I wonder if some of the 3/8"s or 1/2" drive crowfoots were redesigned in the last few years in order to handle more torque? (My understanding is that a regular open end wrench in a given size can usually handle more torque than the same size in crowfoot)
