the motor and frame match, frame #78412,    motor# t110 78412 any one have a reference manual?

"T110 78412" would make it a 1956 *Tiger 110* model.

It should be possible to get a manual from either Bruce Main-Smith:   http://www.brucemainsmith.com/

Or J R Technical Publications: http://dspace.dial.pipex.com/slippery_sam/jrframes.htm

  Hey there, Just wanted to thank you for the info...would that be a 500 or a 650? thanks again!

That would be a 650. And the T110 was the top Triumph 650 model until the famous Bonneville T120 came along.

1958 model T110

The most obvious difference between a T110 and a 6T Thunderbird is that theT110 has an alloy head, just by the way.

Tiger 110 didn't have an alloy head until 1959 (I think) In '56 it was iron but had one more fin than the 6T I believe and certainly larger valves, sportier cam etc. If I remember correctly the 56 T110 was the one that reached 117mph on road test,

I think you will find that the alloy head was actually fitted to the T110 from the 1956 model year onwards.
