Ok cub manufacture date
What's the best way to determine the age of an Ok Cub?

Jim, I seem to remember the .049b with the serial numbers
were exclusive to 1953. Note:seem to remember.
Here's mine with the 128tpi needle assembly retrofit.

On closer inspection, those are patent numbers
on the underside of the engine.
Mine has the same number as yours.

Mark Boeson is the CECF "resident authority" on Cox engines.
Perhaps Mark will "drop in" and tell us how to determine the manufacture dates (as opposed to age)

Jim,
'Til Mark checks in, here's this from his site.
I believe this is the one.

Re: Ok cub manufacture date
Jeez, I wish! Mud is the king of the Thimble Drome world! I've been collecting Cox stuff for twenty years or so, but it’s a drop in the bucket compared to Mud.
As far as Herkimer stuff goes, unlike Thimble-Drome I don't think anybody really bothered to take a lot of notes 'back in the day' or likely save any info. I've emailed Ted Brebeck several times (founders grandson) and he's a nice guy, but he doesn't really have much for detailed info. What info that’s been published in ECJ is pretty basic as well.
The original 'large case' .049/.074 with serial numbers only lasted a year or so, less then two and were pretty much done by '50, early '51. Your .049B came out in 1953 and was in production up into the late 50'S. I noticed it does have the larger diameter knob on the needle, which seemed common up to '56-'57(?), so about the best I can say it’s a 'mid-fifties' .049B :^(...

One you don't see often is the .049C. It was made by adding an .049A tank with an .049B engine via a dural plate. These were assembled from factory parts but not while OK was in production. It's in the upper left of this pic.

Very cool George. Never seen or even heard of the "C".
A+B=C The nuns were right!
Thanks,
Bob
