Vtg 1970s Yellow Ski-Doo Snowmobile Helmet (Large) With Shield & Box

Vintage 1970's Yellow Ski-Doo Snowmobile Helmet (Size Large) With Shield And Box.  Helmet is in excellent condition.  I don't see any scratches, scuffs or marks on the shell.  There are a couple minor scuffs on the decals (center stripe and Ski-Doo side logos).  Interior fabric is in good condition, but it is loose in the front, and the foam has deteriorated like all vintage helmets.  Shield is in good condition, but has some scuffs.  There are 2 extra screws and washers, that I assume are for the shield.  Has original plastic that was on the helmet in the box.  Box is very nice, with minor wear.  This is a super nice helmet with rare box.
