✅ SOLVED What’s this contraption?

[TWray]

I believe it reads Diamond Rubber Co. with a diamond shaped (trade) mark. It seems to work like a pump. With gas cylinder, push rod, and plunger. But I see no vent, intake, or exhaust. There may be or was a hole at the tip of the push rod, but it is boogered up. The internal workings are also shot. My google research shows the name to be a tire co. And the closest image that Ive seen to it, believe or not, is women’s breast pump. Go figure?

Could it be a vintage bicycle tire pump?
