52cm Vernon Barker retro-mod winter bike with chi chi kit

Sadly this needs to go, it is doing anything that my Mercian can't and I need to make a little space.

Frame bought on eBay about 4 years ago now, the parts marked with a * were new when I put on it, I have done about 1200 miles on it since building it up, the overall condition is great but I've added specific condition notes next to the spec below.

Sizing:

52 cm centre to centre top tube
51 cm centre to centre seat tube
100 mm head tube
78 cm stand over
