Making a new thread since there's no other record of this model online and Google doesn't index the "show your new tools" mega thread. Weaver Bulldog jack dates from the early 1930s, rated for 5000 lbs, slightly over 4' long and weighs 137lbs. No grease fittings but pivots and casters are easily greasable, needle bearings in front, ball in rear.
Really cool design that I didn't know existed until this one, mechanism is similar to a railroad jack and uses lever and dual pawls to raise the load, one cog at a time. Walker made a similar one, maybe there are others? The right foot pedal raises the saddle to full height (or until it meets resistance) with a single press, left pedal up raises the load, down releases it, also one cog at a time. Trigger on handle adjusts the handle position, actual handle range of motion is somewhat limited, unlike a hydraulic jack, so the trigger allows the "pumping" range to be from maybe 90°-60°, 60°-30°, or 30°-0° or so. Bought as a curiosity but I'll probably end up using this pretty regularly. Although I'll probably still use jackstands this design seems much safer than a hydraulic to be under without them. Really neat piece and if someone finds another one out there, definitely snap it up.
