Here's an old one! I've been searching for a very early example for years and couldn't help myself when it appeared for sale. Early features: Small-bump early-shaped tank. PRIMUS on the top, no sign of PATENT on the opposite side. Filler Cap stamped B A HJORTH & Co. Release Screw is plain. Pump Cap stamped F W LINDQVISTS PATENT. Pump Knob is plain. Pump Body is round with the pin drive to secure. Burner is plain/unmarked with the round (non-hex) mounting boss. Base is spun, no makers name but is stamped with a small "T" near the centre. Legs are the early pattern with long fingers at the top The Trivet is a red-herring, its a lovely early trivet but not as old as the stove. It's in superb condition though and survived the journey without incident My excitement was tempered after a subsequent discovery, more in the last group of photos, but I'm still delighted to have it. I would say its a sister stove of THIS example. With the early shape tank, only PRIMUS on the top and the Hjorth Filler Cap, I'd say its from the same narrow time period What say the experts? Side Views: Tank-Top Views: Pump Assembly: Burner Assembly: And the shattering discovery under close inspection...... Stress Cracks: So, a great find but unfortunately I wont be firing it in case the cracks open up. I know theres tank sealer etc to try and use but it's not worth the risk. I may give it a light polish but it will be kept for display purposes, unless of course someone has a runner they would like to swap me for it? Cheers, Alec.
@Rangie A superb score, the early stoves with the cast trivets, just shows the quality of the older stoves
Haven't removed the pump yet John, I need to make up a nice fitting spanner, but looking down the tube its the early style of cork cube NRV Alec.
Nice example of a very old stove. A shame to see those stress cracks. Unless treated(which you already said you won't) it wil never run again
Tiny peg spanners of correct fitting are available but stockists take a bit of effort to track down. But they are small and don't give much leverage if the pump is well stuck. And it all depends too on whether someone in the dim and distant past hasn't already mangled the peg engagement holes
A correct hook wrench will do the trick, but you can also make an adjustable tool yourself by modifying an adjustable spanner with a couple of pegs like I did for my old stoves with this type of pump:
An appropriate adjustable spanner to modify considering who invented them and their takeover of Primus.
Great minds Christer, excellent little modification, I was planning similar.... I was part-way through making up a tool. I machined out a large nut to the correct I/D and a couple of shouldered-screws to engage firmly in the holes (they are quite mangled), but I was a little dejected after I spotted the stress cracks I'll get back to it at some point though Alec.
