BMW M STYLE SPORTS PULLOVER 1980's GENUINE BMW .

Genuine BMW M Style mens Navy pullover. Purchased new from BMW Park Lane London in 1986 by myself. Size is Euro Grosse 50.  I believe this converts to a UK 40" chest. WORN ONLY TWICE!  I found three, tiny pulls in the wool on the front just below the vee (See first picture of pullover in box)  and asked my wife to carefully repull them back. I am a bit of a perfectionist and still believe I can just see them but my wife assues me they are ok! (See photos 5/6/7. The logo 'BMW M STYLE' is on the opposite side of the three colour stripe on the front shoulder.  The 1986 BMW M STYLE catalogue descibes this item as ' Navy pullover: Sports pullover with classic V-neck and extra wide cut for maximum freedom of movement. Top quality. Cotton inserts around shoulders and beneath sleeves'  Original box, where it's been folded since 1987 is in good condition, original clear cover is in poor condition. Cost new £85.95GBP.  To help gauge the size better I asked my eldest son to turn model!
His chest size is a UK 37" (Approx. 94cm) with an inside arm length of  20" (Approx.51cm).  Any questions please feel free to ask. Thanks for looking.
