Ok Eamonn, if you fancy doing some sums on compression ratios or whatever they may be.
I have found what I think is my last Jnr Gent kit, It is not from Dan and is probably over 5 years old.
The bottom tube measures 9.73 at one end and 9.75 at the other externally 9.18 and 9.21 internally.
The bottom flange (nib flange) 9.34 and top is 9.25 external.
I have not measured the top tube as all my issues were at the bottom.
I will make this kit up now and use the larger end for the nib although it's only 0.03 difference which I dare say runs within tolerance. lets see what happens this time init?
