Or "stive" as the almost certainly smart phone-generated heading reads.

I've never seen a Hi-Vue of this vintage.  They've all been the boring look-alike style of the '40s and early '50s.  This one has some bling going for it, and I like the glass visor too.  It makes sense, but it's probably a cleaning nightmare.

It needs major cleaning, but if I were in the market, I'd probably grab it.  I love me some Hi-Vue action!
