I got offered this no label A2, which I believe is a Cable Raincoat contract, at US$500 shipped. working Kwik zip, seems original knit, nice patina, small nipple snap rather than ring snap. 1) I see it HH in the photo, + using Kwik zip - does it implied it is the 1st batch W535 ac23382 ? 2) Is $500 a good px ? 3) I will wear it, I want to use same mustard tone lining just to cover the missing part near the collar & trim the sleeves to my size. that is. Will you repair the lining just near the collar or replace it altogether - I seen one from John Chapman before ?
