The first in
my list is (was, thanx!) 82S2194
If I'm not mistaken (it's likely I am) the first 50 or so, had the decal and the first 100 or so, were Solid Koa.
The decal was not an option, they just came with it (until people started complaining)
Mine is 83S2674 and the one I sold is 83S2433
It?s difficult to determine the rank since they not only made Spoilers back then.
With yours it's a bit easier since it is one of the first ones -> the oldest known to the club according to my list. :-)
