Looks like a "32-2" built during 1969-1978, so different from the 32-3 and 32-200 built later, and also different from an earlier Ericson 32. There are similarities, but also many differences. In any case, you have a good boat and it looks great in the picture.
I graduated high school in 1973 and I retired 5 years ago. Holy Cow! Maybe you can post some pictures showing what 50 years of dedicated ownership of an Ericson looks like!
