note on Chiementin -

posted some images of an example in forum tread here a couple years back

checked just now and they have gone up the chimney; also no longer on me hd

Chiementin is the name of a retail shop located in Venezia

possible that all cycles bearing the name are contract builds

here is a forum thread we had on one done by Galmozzi -

​​​​​​Galmozzi-chiementin

you may wish to begin a thread on your example when you are ready...

note on measuring tube diameters -

you can get fairly close by wrapping a piece of paper around a tube and marking it with a pen

you can then straighten out the paper and measure it with a straightedge and divide the result by Pi

another technique is to employ the jaws of an adjustable spanner
