Need help identifying strange tool

[Kscardsfan]

I’ve been slowly cleaning and organizing the tools at our headquarters after what I can only assume to be decades of neglect have occurred. During the course of emptying some drawers yesterday I found this one. It looks and feels factory made. I initially thought it was a speeder, but now I’m thinking it’s a tire tool of some description. It’s about 18” long and has approximately a 3/4” 6 point socket forged into it. Any help would be appreciated.

Scissor jack handle?

Some old socket tool lines used to have individual tools for different sizes, which could be what that is.

It's a wrench to lower and retract the stabilizer jacks on a travel trailer.

It's a single-size speed wrench. Much like a single-size nut driver (I don't use them; I have a screwdriver-handle 1/4" driver in my box that I use with sockets). Not very common. I had two very nice speed wrenches and gave them away because I never used them. Don't miss them either. Now for a job such as on those stabilizer jacks as mentioned above where you are cranking them for a lot of turns, it is the perfect tool short of a cordless impact driver.

Many of these old engines, like my RUSTON HORNSBY, have a boss cast into the head of the valves. The idea was, this supplied tool could lap the valves to a good fit.
The Engine. The engine is a single cylinder Diesel. It is 10.5 liters (640cid). The weight is 1915 kilograms. (4000 pounds) I have had this engine idle down to 58 rpm. The top operating rpm should not exceed 250 rpm. I have owned this engine for over 40 years. The information I have suggests the engine was made in 1932 in Lincoln, England. This engine was used as power in a Canadian grain elevator in Alberta. The engine has an air start option for those times when the operator does not feel like using the supplied 15 kilogram, two person crank. Yes, I have started the engine with the crank. I had my neighbour trip the decompression lever when I got the crank speed up enough for a start.
I am designing a friction start which will use one of my IHC LB engines

As other have stated, it's a travel trailer stabilizer jack crank.

That makes the most sense. It’s a state park where I work and people leave random stuff behind all the time.
