n°11 Hasag stove

Hi all
I found this Hasag stove
Seems to be old but I don't know
the first inspection tell me the beast is complet
Who have an idea of the period ?

 

it seems nobody knows this stove

 

As it looks very much "made for France" in the design and the markings are "pre 1928" style i would suggest it was made in 1920's - maybe as part of war reparations that seems to be usually erased from company archives.

 

There is another Hasag No.11 in the reference gallery (here), and also a couple of the very similar Hasag No.10s (here & here). Weimar period, 1920s into very early '30s, does seem to be the most likely dating but no documentary information around at the moment.

 

thank you all for these advices and links
it is a shame and very odd to find so few papers for such a great firm
Yes, the n°10 is very close of this one
We shall see now how it runs well

 

Hi all
while the stove was quickly and badly cleaned
I heard some noise in the fount,
and I found some big rusty shavings of steel.
So I decided to go and see in the tank and I unsoldered the base of the burner.
Just between the base and the dip tube, one can see the rest of the iron part which was soldered
I have absolutely no idea of the shape and the utility of this part
Have you an idea ? Have you seen this on another stove ?

 

There use to be a steel plate as reinforcement inside top of the tank as @kerophile show in this thread: Valor No.51 Dissection.

 

OK I thought of something like that, thank you to have confirmed the fitting technic
I shall try to resolder without this iron plate because I should like to avoid to cut the bottom
have a good day

 

View attachment 227061 Hi all
here is the burner base resoldered and the stove cleaned
Now I have to redo the pump's leather which is bigger than the standard ones (circa 25 mm)

 

Excellent progress.

 

here is the big stove running very roaring
I have had some trouble with the NRV

 

Hi @Michel Lovely stove and powerful flame pattern. It will perform even better with flame-ring:

Why Do You Use incomplete burner?
"flame ring" is important

 

Excellent, well done. Re your: "... very odd to find so few papers for such a great firm"
Wars have major affect on the research for many a great European firm. I presume you've already searched: Hugo Schneider.

 

@OMC : I presume you've already searched: Hugo Schneider.
Yes I searched, but this don't gave me many informations about Hasag papers ;-)

@gieorgijewski : Why Do I Use incomplete burner?
because I havn't for this Hasag
I have to search for one, because this is almost impossible to find original one
if somebody knows where I could buy a replacement, please tell me
I think the diameter to be circa 4.2 or 4.3 cm
this Primus (4 cm) is a little too narrow

 

According to Kerophile topic it could be 41 mm diameter (??)

 

@Michel The roarer flame spreader available from the Fettlebox would be a good option. Should be right size and doesn't have any unwanted branding on it.

 

Hi @Michel the 41mm diameter flame ring-ring is the most common size, suitable for the burners used on 2pint and 1.75 pint stoves.

Flame Ring - (brass) for Roarer Burner - The Fettlebox

Thanks @kerophile I shall ask for

 

the difference is not obvious, but it is complete
