I'm not sure what you mean by 76er, so no it's not. It is a "war years" Westfield originally had zero chrome and it's my understanding that you had to apply to buy one and prove you needed it for work. It was also just about a basket case when I got it.

That's an old aftermarket chainguard too, not the og. Bike looked green and I almost passed on it but a little rub and I realized it was blue. Fork was bent and broke, rewelded crooked. But the blacked out gooseneck and a decent piece of skiptooth chain with the patina'd blue made me grab it anyway.
