Interesting Hub Cap Wrench

I have what appears to be a mid teens hub cap wrench. The style is common, but the markings are not. There is an M with a diamond around it, and just below that is a circle with a P. It can't be to common?

Larry, the M in a diamond is the mark of Mosberg tools. It may be an aftermarket item.

Larry,
On the subject of hub cap wrenches---------------
What is the smaller octagon hole used for on the bottom wrench in this photo?

Maybe it’s for later model engine pan oil plug?

I think the small hex fits the front wheel bearing lock nut, the other one fits the threaded bearings.

But, what is the smaller octagon (8-sided) hole used for?
I have not seen an octagon nut on a Model T.

Hmmm? Looks like an earlier style Ford wrench. What could a '09 or '10 have that later cars would not? Water pump nut would require open end. Maybe not Ford?

The bottom wrench is not Ford. I have been told that it is for Chevy. They are easier to find than the Ford one’s and easy to confuse if you think you have made a find and not pay attention to detail!

Jim: I've seen those wrenches too. They are exactly the same as the Ford wrench, but have 8 sides for the small octagon. I have no idea what they are for, but definitely not Chev.

I believe that smaller octagon is for the crankcase and differential plugs. The early plugs were slotted so the early wrench did not have it. After the change the later crankcase continued to use the octagonal plug but the later differentials used a plug with a recessed square. The later adjustable wrench had a square end to use for that.

Charles, you are absolutely right about confusing early 3 hole T wrenches with Chev items. I found two such items at 'Ford and More', [now Model T Ranch] in Spokane and thought I was Christmas. At the counter, cash in hand, I realised the big end was hexagonal!

Val, I have never seen an octagonal drain plug on a T. The usual hexagonal plug is 15/16". the same size as the rear axle nuts.

Since the drain plug is a hex, how did you come up with that idea?

Octagon will fit a square nut it has four flats in side. You can buy 8 point sockets to day and 4 point sockets both are for square head fasteners.

You will not get much leverage on a square fastener with an octagon wrench.

Oops! Allan, obviously, I can't count. Six, not eight sides on the plug

An 8 point socket fits a square nut also the octagon wrench may be for light duty such as top prop nuts where the original was lost. This may be for the British cars as many early British cars used 8 point nuts and bolts

I have built up a collection of 8 point sockets in 1/2" drive. Some are two different vintages of Snap-on. They are very handy when working with coach bolts and square nut when building wooden bodywork. I paid US$13 for a 9/16" Snap-on one on ebay. You can guess where that one gets most use.
