Natter, My e-mail adresse is toke.norby@norbyhus.dk and feel free to send me the drawings etc. which could explain what I have :-) It seems that 1 and 3 are "a pair" even the outer diameter is different No. 1: 44 cm and 12.5 cm for the axle and for No. 3: 46 cm and 11 for the axle. No 2 is totally different from the two others. 1 and 3 are conical and 1 "fits" to 3. Mvh Toke

Hi Natter, Sorry you couldn't find my page but I moved it when I changed internet provider early in 2010. Now you can find the page here: http://www.norbyhus.dk/maritime/torpedo/ Enjoy Toke

Hello Jesse, Happy New Year to all! Well, I know very little (close to nothing, I'm afraid!), about torpedos but there is a similar discussiongroup in Denmark where I asked and got this reply (It's my translation into English so please bear with me!): "It is with 99% certainty a prop from a T1T. After the 2nd World War II the Danish navy "inherited" many T1T from the German Wehrmacht. In fact so many that they up in '70ties used them before we got a Swedish built TP612 which was TP613. T1T was a battery-powered torpedo, while the Swedish, which was further developed of the German one, was steam-driven. Highly concentrated peroxide, approx. 96% pure, distilled water and pure alcohol may cause a combustion in a closed system, thereby creating steam. This way: The engine is a star engine, it is in a lot of trickery, but one thing stands out, the steam producing part which is a small case, it is the size of 2 ½ L soft drink bottles. Entering alcohol and water, and peroxide when contaminated with water and alcohol, split it with such force that it ignite and this creates a chain reaction where the alcohol is burned off with high heat and evaporate the water. The steam is now being carried out to the engine. The excess pure oxygen also through the "exhaust" intends to torpedo, and will shut off quietly, so the torpedo does not pull a bubble trail". But that's another story even the props may be the same? Mvh Toke

Dear all, Please take another look on my page but scroll down to the bottom as my third torpedo prop arrived an hour ago (the seller had mounted a watch in it!). It seems to fit to the small one I show above as they both have the "pointed teeth". But I have no idea of how old they are? probably post war props. http://www.norbyhus....e/torpedos.html Mvh ("Kind regards" in Danish) Toke

Hello Joe, You are right but it's the smaller prop you see more clear than the bigger prop below, so I have taken a few photos and uploaded them to my home page: http://www.norbyhus.dk/maritime/torpedos.html The photo below is not from our sitting room (!) but from our Danish Naval Museum - as far as I remember. I couldn't find the mail with the link, though - but i'll find it later. The pointed teeth are very sharp as the prop probably hasn't been in use ever. The bigger to the left seems to have been mounted and has some repairs here and there on the blades/wings. The number 15031 on the small photo is also stamped in the metal like the "89" - and not from the casting mould, sorry. Mvh Toke

Dear all. Greetings from Denmark! I found this forum while searching for info on torpedo propellers. In 2007 I bought the upper propeller and a few month ago I bought the lower one. They seems to be a pair. There is no sign at all on the small one but on the bigger one (which is like Jesse's) there is a 15031 from the cast forme and a "89" stamped in the metal. Now I need the rest of the torpedo! Just joking - but I thought you would like to see the pair. I have "a few" more normal propellers but I could not resist to buy these two ones. Best season greetings to all! Toke http://www.norbyhus.dk/
