I've had a couple of classic Silca's one was black exactly like the OP'rs, but lost it while supporting a Leadville 100 team as a mechanic somewhere.
This one had a bad leather washer which I replaced and a bad hose, which I replaced with this dual head Sunlite thing which is my favorite chuck head. Way more functional but these pumps are better for 28c tires and smaller to dial in the exact PSI needed.
