I've had this old westport cruiser for quite a while, I occasionally ride it just because of the weight, I found out this may be one of the USA made ones, How do I tell the difference, were they all made here, or some in China? If it's made here, I'll probably put a little time into it, when the Schwinn is done, Especially since Murray was originally out of Cleveland and I grew up only 30 miles from there, it adds some sentimental value. I understand they can also be upgraded? I thought about possoibly converting to a three speed, but I dont have much excperience working on these old coaster brake type bikes
