Well the original Optimus lanterns were also Petromax clones, so in a way everything you say is correct. :)
Very interesting. Definitely a copy of an early Optimus 200, or maybe an early Petromax 821 but going by the pump I'd say it was an Optimus they...
An Optimus 4a mantle is what they would have come with originally, but any 300 - 400 CP mantle should work. There are many brands to choose from...
@Jean J I think you got the dates swapped around from the other post. It was the 350 that was from ca. 1960 and this 1350 is most likely from the...
Welcome to the forum. It looks to have cleaned up nicely. The tube is only needed to assist in lighting the lantern. In most cases it will start...
No, the string was very thin and usually didn't last too long. In normal situations it wasn't really needed. Another idea is that people didn't...
When they came from the factory, that strip was bent down so it was along the edge of the cup. It had a piece of asbestos string tied to it that...
I'll just add to the info already given. The 350 is most likely from around 1960 (ish). The 1350 is probably from the 1970s.
The lid fits, but the screws are a bit too modern. :)
For some reason I have found more 1050/1051s with rounded off NRVs than other models. I assume it has to do with the larger thread diameter of the...
The enamel on the hood looks to be in excellent condition. That is a good find. Are there any traces of nickel on the brass parts? Primus did...
I think you will find it is for the Swedish word "gängor" or short for "gängor per tum".
There are a lot of threads used by the Swedish manufacturers that are not standard. Primus is the best (worst) example of this. Usually they used...
The jet thread is the standard type used on all Optimus lamps. It is 7 mm diameter with 24 threads per inch in a Whitworth profile. I have never...
I have seen this before on the Optimus pre-heat cups and also wondered why. There must be a reason for it. My guess is that it creates a jet of...
Well done Darryl. I am sure the thread is #2 UNF, but that is so close to an M2 that it wouldn't make much difference.
Welcome to the forum Hippi. As James has said, you have most of an Optimus 252. It is missing the globe and top. Here is a link to my example, so...
I might as well add my personal opinion. I don't think there should be a dedicated section for wick lamps. As mentioned before, this forum is for...
Now I wonder what collectors of industrial vacuum cleaners would say to this. ;)
The 1094 has the quick start torch added. That is basically the difference between the 1092 and 1094. Usually the 1092 was 350CP and the 1094 was...
Separate names with a comma.
