Vintage German Missler Blowtorch (from 1943)

Description

I am not 100% positive, but going off a note I found with the torch.     this was a torch in my father's blowtorch collection,     According to the note, the Torch was made in 1943 and the German Army used it for preheating vehicles.      It appears that the backside of the plastic control knob may be a little damaged.
I think this was manufactured by Tecalemit  and the model number is most likely K5512 / 3.      The word "Missler" appears on the end of the control knob.
Shipping cost is actual cost....no handling charge.
Please ask any questions before bidding.    Thank you.
