That 'filler cap' looks like a pipe fitting so maybe the thread is a standard pipe thread?
That's an interesting find. I've seen railway ones before but not main roads. The disc at the top is interesting. I wonder what the idea was.
That's a nice one you have there Darryl. Not at all that common. That attachment of the tripod was only made in 1959 and 1960 so there can't be...
Yes the 992 is a good lamp. They work well and look good. A bit noisy though, but in a good way. :) In 1955 there should be a red metal plate...
I am fairly certain that the 1551 wasn't made until the 90s. Maybe the very late 80s. The predecessor for the 1551 was the 1550, which started in...
I have never seen any proof that this is the first version of the 1551 but all evidence points that way. Quality wise there is not any difference...
I did a quick search in the Australian War Memorial photo collection for WW2 and found the following photos. Unfortunately they are quite low...
Considering the lack of known original shades of this design, it is not possible to know how well they fitted. From the pictures I have of the...
I am almost certain that is not an Optimus filler can. I am also fairly sure it is not a commercially made item. The brass looks to be good and...
I have seen one other 1015 from 1928 or 1929 with this shade and it also matches a 1929 catalogue picture (as Frank mentioned), so I would expect...
Is the shade in the first picture the one that was broken or the one you now have? I believe it is the first variation of the shade fitted to...
The mark is the optimal pressure, which is around the 1.8 bar mark. These gauges are not a precision instrument, so the marking should be used as...
This is actually a kerosene lamp. At least that is what is written in the catalogue referenced in the other thread.
Just for info. It is quite possible that the very latest Optimus lamps used M7 x 1, but most of them used 7mm x 24 tpi Whitworth (the 100N used M7...
I believe this variant started around 1939 and continued for the first half of the 1940s.
Do you have any history of the shade? Could it have been something that Kopsen or Nettlefold had made? As you say, it looks very much like a...
That's something I havn't seen before. Good to see. Two different ages of burners as well.
Apart from a bit of a clean, the lamp is as I received it. I do know the parts you mention are wrong, but it is not normal for a collar to be...
@Marko57 Do you have any photos of the burner? It looks like the SwiftLite burner. I have a Handi configured like this that has the SwiftLite...
This is the last version of the 1550 and was made towards the end of the 1980s. It was from the time when sales were declining for Optimus and...
