CBJoe.... sorry, no idea. Small one was from KIJIJI and the larger one came with a bunch of bikes and stuff I bought all together. Both Made in China, for sure. The large one operates with the foot pump (hydraulic) or compressed air. Never use the air, it’s not smooth! Works great, on the pedal. The small one was like new, but all the paint came off the top bed. Rusty chequer plate underneath. Had to clean and paint it myself.... cheap stuff, but useful beyond belief.
