I think what you have is the typical '20's / '30's many types / brands were
made BSA style wheel-hub nut wrench.
If you look at an old BSA rear hub, you will note that the RH axle end has a
square.
Many old English and other hubs of the era had an internal shoulder on the
right hand side, both front and rear.
The right hand side then would keep the RH cone tight against the shoulder
and was not adjustable. The wheel rotation kept it snug and it stayed tight
against the shoulder so it wouldn't tighten on the hub bearings. That's why
the right hand cones were usually round with no cone wrench flat.
We used to grind one in so we could take it off easier without having to
tighten it in the vise and unscrew with pipe wrench or the like.
All the cone / bearing adjustment was done on the left side.
It also meant that if the outside nut came loose, the cone would unscrew
with the wheel rotation and not crush the hub or freeze and flip you over
the bars. Whooie!
This kept the cone and locknut snug against the inside of the left fork tip
and all rolled nice in adjustment with light oil and the click - click of
the bearings as they fell over the top of the race. Aah, music to my ears.
If the rider / mechanic was clever / talented, it was possible to adjust the
back cones and not remove the wheel by tightening loosening outside axle
nuts and turning the axle by the square.
The offsets on the wrench were for front and rear axle nuts.
It was obviously easier if one had a thin cone wrench.
It was also possible to adjust bearings on the rear wheel without having to
use a vise.
But it was allowed to have a vice.
