Triumph 3hw information

Recommended Posts

Good morning everyone, I have been looking for a Triumph 3hw for a long time and now I have two to restore (almost three) .I have seen that it is possible to go back through the chassis number and data including the registration number on the tank ... I don't want to be too indiscreet but someone can help me ... thank you for your time.

TL 34216. Tec 1.43

TL 35774 Tec 3.44

The chassis number 35774 has two small marks at the beginning and end of the numbers and the other one does not have  them..

Hi Moreno .

Great finds ..There is a register of Triumph military bikes at wdtriumph.com you may want to get your bikes on the list

also if you are actively buying bikes you will enjoy British military motor cycles 1924-1945 by Chris orchard and Steve Madden it contains manufacturing tables which may find useful . Triumph bikes are heavily stamped on both the engines and Frame ..so photos of the engines may reveal more

Frame 34216 Jan 1943 ...this was contract number C13948 frame no.s 30923 to 36417 the matching engine number will be  3HW 40923 to 46417 the seat  post manufacturing date shows Jan 1943

The second frame is more complex the frame number would suggest it's in the above contract but the Seat post date is later at March 1944 .......The offset stamping on the frame is unusual ..my suggestion is that frame was a spare military frame that was restamped  when the original  was damaged beyond repair (not uncommon in the war ) The stamping is likely to have been done at a REME workshop rather than the factory.

Photos of the engines and stamping may reveal more....

thank you for the information, I have seen the triumphwd site and as soon as possible I register with my bikes.I believe that you are right about the chassis n.TL.35774,I did not think that the engine number is also important for the identity of the bike, now I send the photos ..

TL.35774.        Motor . 53847

TL.34216.         Motor.  44216

Moreno ..Thank you for The photos of the engines .

Frame 34216 is a jan 43 frame and the engine number is within the expected range at 44216 if you look between the 3hw and the engine number you can see the war department stamp for inspector 52 at the triumph factory ...both contract 13948

Frame 35744 is a genuine March 44 frame but the appears to have been stamped with an earlier frame number potentially at a TIME site The engine number correlates with the March  44 date it was produced for contract S2956 between December 43 and June 44 ..the engine range for this contract was 3HW 51418 to 56417 ..so engine 53847 is in that range

Both Engine and Frame are from the same contract S2956 .....again of interest is the war dept stamp is not visible on the photo of 53847 ..is it visible elsewhere ?

Hope the above helps.

Jenk, if you haven't noticed? Engine 44216 is the factory matched engine for frame 34216.  Ron
