Can you date this Utica ?

I found one listed at auction , but it only said Antique wrench.
I had some newer Blue points of the same design.
Not sure if Utica made them for Blue point , or the patent ran out.
I just bought for wall hanging or to pass it on.To neat to leave it lay
The number is 43216.The bluepoints were stanmped steel riveted,rather than forged.

Thanks Franklee. Looks like orignaly they applied in 1946 and abandoned the patent and reapplied.
I like the drawings , must have cost a lot to build in it's day.
It's pretty hefty for it's size. under 6"
Thanks again,I need to get more experince on how to search this stuff out.

This moveable-pin opening led to the forged Loc-Rite broaching of Bonney wrenches in 1964. And as of the 1986 catalog I have they were still offering these Cam-Loc wrenches.

Another feature unbeknowest to the original designers was the fact that these SAE Cam-Locs can be used on metric fasteners. The inherent "give" of the mechanism allows it to fit a slightly bigger metric size. Your 1/2"er (i.e. 12.7mm) will easily work a 13 mm bolt. So these old dogs can be used in the modern auto shop.

Here's a DOE I have:
