Had a pretty cold thrifting day today, but saw a good condition Sanyo full length raincoat. Raglan construction, removable lining, 100% cotton outer, appeared very well made. Was tagged 36R and fit well generally (I wear a 38L usually), but the sleeves were at least 6 inches too short for me. I have no idea who is that tall but wears a ~20" sleeve length, shoulder to cuff. Bizarre.
At any rate, is Sanyo stuff worth picking up for eBay? Should I go back for this thing?
It sounds like you found the T-Rex jacket.
