This Primus No.4 has seem some heavy use over a long period of time. It's burner was almost completely clogged with carbon, it's legs bent inward to accomodate smaller pots, numerous dings and dents, etc. After some minor cleaning and restoration, it works like a dream. I'm sure it has another 76 years of service in it easily! I have included one pic of it next to an Optimus 00 for scale.
