That would be very interesting to a few l think, if you get the chance? Thanks. Do you want to sell it? :-)

No not for sale at them moment as I had a plan to put together a replica of a bike I had as a teenager. I'll have to get someone who hasn't just had back surgery to climb up the ladder to my mezzanine to get the barrel before I can measure but my son should be over this weekend.

Actually got 2 off them but one has had a cast iron sleeve that I fitted to it and has been sold to go on vintage racer.

John, if you're still looking for DT1M specs I have an article listing hts x widths as follows

EX 39x46

Trans 51x31/17.5

In 100x45 (to bottom)
(75 to top of port)

When I had a DT1M cylinder I measured as follows

Ex 36.5
Tr 51
In 99 bottom, 76.5 top
