Hello my people! I’m currently in the hunt for the same model coveralls that Nick Castle wore in 1978 in my size 52R. Please if anyone is willing to sell a pair to me in that size or finds anything on any platform that matches, please let me know ASAP. I’ve dreamed of owning a pair and having a piece of history apart of my own 1978 cosplay. Thank you so much for your time everyone, please let me know if you find anything. 
Are you also wanting for them to have the top button closure instead of snaps or is just the color what youre after?
I’m looking for the exact ones with the black tag, they’re pretty darn hard to find tho unfortunately…
However I recently just found a guy named Bliss Studios who makes exact replicas of the sears tradewear with a price including weathering and accuracy at $250! What a steal in my opinion! And it’ll arrive before Halloween, which i’m super glad!
$250 is crazy, my tradewears were like $40
