UPDATE....here are some pics..the# on it is actually T1139N...only ones I can find...curious to know what you guys think about it,as far if I should buy it,or walk based on what you see....thanks..


I recently came across a pre-unit project that I am intrested in..been wanting one for a while and I like what is there with this one... But before I go any further pursuing it,I wanted to check to see if anyone here could shed some light on the engine #...That is T11139N..
Can't find any other #s on it anywhere else,and I can't find this on the site I usually go to for info..and of course like so many old projects.. its being sold on a bill of sale.... close as I can figure,it is around 57-8...just trying to determine what exactly it is..
Any help appreciated...

T11139N..
Nothing about that number makes any sense, N suffix is real early, in fact I think they stopped using the suffix altogether between 52 and 83.

If the T is part of the engine number and not the model number, it would have to be a speed twin, pre 50's

Even a 54 T110 would have had a 3 digit number for example T110 101

I have heard of some American market & Military/Police models having strange numbers and prefixes

does is look factory stamped ?

Previous to 50 the year is part of the engine number. From 50 up it is just a model and number, the year is determined by the number itself. The N suffix was in 50, then NA in '51 after which the suffix was dropped. But no N suffix '50 number has a T as the first digit.

First thing I thought of when looking at and seeing it was the # couldn't be correct..
I am used to seeing (as you all pointed out)..the prefix typically being the model..(T100,T110,etc)
I looked at the numbers and the surface behind if for any signs of alteration,of which I see none...
I have some pictures stored in my camera of the motor and frame..which I wil download and post tomorrow..
Hopefully at that point,you can all tell me if I should move forward,or walk..
Thanks for all your help thus far...Rick

Looks like you have a 6T Thunderbird... maybe. I have not seen the - between the 6 and the T before... The T looks correct without the serifs and it doesn't look like it's been ground down and overstamped.. BUT here is where the experts can chime in: this one is a generator style but it's in a swingarm frame... very curious for a 6T.

By the way, that is a later 9 stud top end, interesting intake runners as well. I see the shifter is bent and the swingarm frame has a welded on rigid rear... your best bet would be to just send it up to me.

Yep +1... 1950 Thunderbird 6T with 60's 9 stud twin carb top, the date stamp inside the rocker cover should give more of a clue about the head. looks like a cool project
