Petromax 827

[Colin M]

Hi All,

Picked this one up over the Christmas period, a bit sad and sorry but worth the money.

According to the " New " dating of P'max this one has scratched on it 10 66 or 99 01 depending which way you look at it. Doron has pointed out the older style Rapid burner.

Maybe Harald used this one at the Battle of Hastings !!!!!

addendum... Have done a bit of searching into the logo [ with E ]. Lantern appears to be pre '53, 200 cp stamped above rim at bottom. The "Petromax" has the line from the P to the X I know dating P'max is a minefield so I will leave that up to the experts. Would appreciate an answer if possible.

Hello Colin! This petromax is definitely before ww2. It's strange that you see there four digits. As this lantern comes from thirties there should be only three digits. Assuming that the "1" is only a scratch, it would be 06 1936, what would make a sense. This type of preheater was patented in 1934 or 35 (I don't remember exactly). Even without these numbers I would date it from 1935 till 1939.

Best regards
Piotr

OK Here we go,


Up & Running, very pleased with the dent removal 99.5% there. Only marks that remain are the creases which will buff out if I decide to take it back to brass. There are a few other minor dents but too hard to get the SST in.

Piotr, thanks for the info. More research is needed on my behalf to get it straight in my head.









Initial Rapid Burn



Generator Kicking In



Waiting, Waiting, Waiting.



Full Throttle




For a rated 200 cp Lantern it puts out a lot of light. I reckon about the 250 - 300 mark. Beats any Tilley I have.

Another Toy to play with.

Very pleased with result, onto the Baby Petromax .....

Colin, how did you get the dent out?

[Colin M]

Hi Doron,

After a lot of R & D I have come up with :

SST 1 [ Special Service Tool ]



SST 2




SST 3




SST 4 [ This one fixes any problems with Lamps ]




It is then just a matter of maneuvering into position and gently work the dent out. The hardest part is determining where exactly the end is so that you do not put more unwanted dents in.

Colin I must say I am impressed!
I thought of many methods but that did not come to mind
do you do outsource work ?

[Colin M]

Hi Doron,

Outsource .... No, I have enough Lamps with dents, I don't need some one else to put more in them. I have no problems in doing that my self.

[Piotr Tumidajewicz]

I'm also impressed with your dent removal skills Colin!
How did you straighten the globe cage rods? Is it loose now or you made it stiff somehow?

Piotr

Hey Colin ..... Can I borrow your SST 4 to 'adjust' my Hipolito please ?

[Colin M]

To All,

Postage would kill you Andy,

Piotr, I turned down a large bolt so that it had a flat surface on the end, by positioning at a tangent to the bend was able to straighten out eventually. The rods are tight. but you do have sideways movement but this normal enough.

These lamps were sold in the UK as Aladdin-Petromax from 1937 to 1939. Here is an image of the pre heater types with dates.

The actual patent application date for the first is 13 September 1935 but no examples exactly matching that patent have been found and it seems to have been first used in 1937 production. It was probably replaced by the second type after 5 September 1929 when the second type was patent applied for.

Thanks Everybody,

I can now stick a label on it.

Hi all !

Thank's Neil for the input on the rapid heater styles, it makes sense since mine seems to have been made in 1937 ( according to those scratches ) and has the early style Rapid heater, it's a litte confusing though, that my lantern has an nickel ( or maybe Chrome ) top vent that is embosed Petromax made in Germany and that old style rinse needle wheel, rather than the typical Red porcelained Rapid top vent , and the more mordern wheel, shown in the 1936 catalog,




Do you know if the petromax lanterns made for the German market used the 200HK stamping, rather than the 200CP stamping ? Mine has the 200CP stamp, maybe export models were different ?

Regards Frederik

I have no information on when Petromax fitted red or plated top caps. I have seen a 1927 type Aladdin-Petromax 900 which has a blue label on the collar and a blue control wheel. This lantern is missing a top cap but I did wonder if that originally might have had a blue top or perhaps a plated one.

HK and cp are not the same. One Hefner Kandel is only about 0.91 cp. So for instance 500 HK is actually 450 cp. I have always been curious about this because they seem to have marked the lamps as HK and used the same number as cp when they are actually quite different. I don't suppose they actually made the lamps more powerful to make the cp rating accurate and this might explain why it is so difficult to find a Petromax type that will actually make the higher power since the burner is designed to do 450 cp not 500.

200 HK would be 182 cp which is not so very much different. I have never seen a 200 cp Petromax marked in HK although I would expect it is something they would have done as that was the measure in general use in Germany in the 1930s. ::Neil::

Petromax marked the same lamps in HK as well as in CP. For example a 1942 military Petromax 827B is marked 200CP on the tank and 200HK on the collar plate.
