Glad your happy with it. They are a good reliable lamp. You'll find that the lamp is a good heat source in itself. I have several heaters, but...
Well done Frank. That's what you call a result. The lamp will be from around 1930 to 1932. Have you checked the date code on the base?
Very interesting, never seen one before. Is there any paperwork that shows this model? I am thinking about what the original shade/globe would...
Well said.
That definitely looks more AGM than Quirks. Probably the model that inspired Quirks to make their own. The details are a bit more stylish /...
Hi Mads and welcome to the forum. As mentioned, you have an example of an Optimus 300 from around the middle of the 1940s. It looks to have...
The top part definitely looks like it comes from a Radius 143. It even has a Radius glass. Don't know about the rest.
I will be interested to hear how it goes long term. My concern would be that there is much more heat transferred to the mixing tube now which...
@Dean D Shinzo has given you almost all you need to know, but I'll add my thoughts as well. If the top of the NRV is so bad that a custom tool...
Primus does not use a standard thread. This thread is 7 mm diameter but has 28 threads per inch with a Whitworth profile. The 1381 should...
Actually, the Primus 1020 jet thread is unique to Primus. It is actually 7 mm diameter but with a 35 thread per inch Whittworth profile. This...
You say it holds pressure, but how long does it hold pressure? The symptoms you mention could indicate loss of pressure. A service and replacing...
Because it is made by Høvik Verk, I cannot be sure when it was made. I do know that the equivalent Primus model of this variant started towards...
I had forgotten that a lot of parts are being reproduced in Taiwan. It's been a long time since I last looked. I might have to make an order...
I'm afraid Frank is right and these cleaning rods are not available anymore. You either have to find a used spare or if someone can produce a new...
If all the parts are original, then that is correct. A best guess would be in the period 1934 to 1938. The mixing tube and chamber on these are...
Good to know it is still for alcohol. I find they work well. Just remember to drain the tank when not being used for while as the alcohol is not...
The primus is labelled as a 1320. Is it still set up for alcohol or has it been converted to run on kerosene?
Separate names with a comma.
