Unknown bike
« on: October 22, 2009, 09:25:07 PM »
I would like to ask if someone knows this bike. I can not recognize type. I think it is some english mark. I found a "New Hudson" note on the seat, but I didnt find any New Hudson with this frame.

It's a Triumph C-Series frame (Models CN, CO, CSD, CTT) from 1929-32. If you let me have the number towards the top of the headstock, viewed from the front, and/or on the lug under the saddle position I will be able to give an approximate dating.

Thanks for answer, so I attached new photos. But I don't think it is Triumph because I didn't find any picture of the types you wrote with my frame.

If you think the triumph specialist is wrong, what do you think it is?

Its definatly Triumph. The reason you may not be able to find similar photo's is because the frame has been chopped. It looks like the bottom end is grafted on from another frame. Also, the rear wheel cast lugs have been chopped off and some sheet metal welded in place, and also some of the tubes appear to have been heated and bent to fit the bottom rails.

The best thing to look at is the top tube being bent to clear the OHV engine and compare this to the CTT, they are the same.

In other words, it's now a Nothing frame, and worth the same amount.

Hi all,
What a fascinating hobby we have - almost an infinite amount of hardware to contemplate - consider the range manuacturers around the world at different times, then add in the backyard fiddler who modifies this and that to suit needs or preference. Personally I like looking at old bits, photos or whatever, and it's particularly satisfying when we learn something from the exercise.
I wonder should we revisit some of the thoughts in this thread?
Our original poster Peet_K asks what he's got, posting a clear photo and telling us it has "New Hudson" on the seat. Peter C replies "It's a Triumph C-Series frame (Models CN, CO, CSD, CTT) from 1929-32." This sounds pretty defintive - Peter tells us the frame IS Triumph, no ifs or buts. He doesn't say "highly modified", "slightly unusual" or anything like that.
Our original poster, probably having been to Peter C's web page where the C model is described http://users.actrix.co.nz/cornelius/Triumph/ModelCN.htm , notes that it doesn't look too much like any Triumph that he has seen, and posts some more pictures (interseting punch set used for the frame number!). ColinB seems unhappy that the triumph specialist could be doubted (and asks Peet_K what he thinks it is - he doesn't know, that's why he posted!), and m3bobby states uncategorically that "its definatly Triumph" but explains the major modifications where the frame has been cut and shut.
Peter C. finishes off with "it's now a Nothing frame, and worth the same amount", which seems quite a shift from the previous day when it was a Triumph C-Series from 1929-32.
I wonder where this leaves Peet_K? Has he learned anything? Have other forum mebers learned anything?
Unfortunately I don't know a lot about early 1930s bikes, but  I do know that the frame is quite unlike the Triumph C-series frame as shown on Peter C's webpage, but perhaps Peter C or m3bobby can tell us more. As to being worth nothing, quite the contrary! Good bits here, if only we can identify them.

Well said Leon, one never knows when these small details will be recalled and help to complete a bigger picture somewhere.

I firmly believe that it's not possible to know too much about old motorcycles :)

I respect all facty ideas, but to my mind it isn't Triumph C-Series (Models CN, CO, CSD, CTT). I attach a picture with engine Triumph 350 OHW. 1)The lever has a wrong shape 2,3)No holes 4) The frame so near the engine. There is of course more differences, but these are the general.

 :)I have no idea what the original frame was as it appears to have been shortened by may be two inches at the rear I am wondering if the original had a larger back wheel may be 21-20 in and 18 or 19 fitted as a motor the possibility of a JAP as this was a very convenient engine to purchase it may be that you're never know what it originally was but it certainly worth keeping it only for the castings and the front forks (if you're thinking of dumping it dump it my way)and remember  back in the late 20s and 30s you could buy your own frame head  casting and make up your own frame if you are good at brazing so the possibility of some enterprising lad rears its head it well may be that was was a giveaway to someone who had ideas of making abetter motorcycle if so I hope enjoyed the exercise as we all know what happened to the British motorcycle industry.
