Old Hein Werner O-Boy - Help Determining Vintage

[floyd]

I have picked up a few HW 1.25 ton service jacks over the years. Hoping someone can help me figure out a date of manufacture range for these two types.

The dark blue one has a more narrow lift arm and no “1 1/4 Ton” casting. I assume that’s an older model? Also, any guesses of what brand the blue one was sold under? It is a very dark blue and had yellow front wheels.

Thanks!

Is the blue lifting arm a welded assembly vs the cast (or forged) red one?

I’ll double check tomorrow, but pretty sure it’s cast.

Here’s a pic of another one just like the blue one I have. Not mine. They have smaller rear caster wheels as well.

The blue one was more than likely marketed under the Walker brand, Model 883 to be exact.

Thanks Hiball. Any estimate on when HW beefed up the 1.25 jacks? Just curious about a general date of manufacture for the blue jack.

Mine is from the 1960's. I got it from a '60's drag racer's crew chief.
