Manx Club

hey guys/girls, have an opportunity to buy and am trying to find out what year(s) the manx was produced without a number tag? it has battery box and spare tire well.i know i've read about these before but cant find the thread now
edit:it has been authenticated by winnie.
thanks
Tony

nevermind, the buggy is sold but i believe it to be a pre tag manx! a good buy to somebody at $2000.
