looking on gmaps, exeter is much nearer me, cheeky me! Taunton is nearer you...would not want to risk posting it, bad exp on planes with mates bikes...any good? where are you, Bristol city?
I'm guessing it's possibly sold? Looks a nice bike and btw I'm 5'7 too and own a 17" & 18" lava dome and a 18" Hahanna and a 19" cindercone all retro, so 18" will be fine for you.
I was tempted, but fear I may be turfed out my own house if I buy another
