Hi, Kevin,
I've had a look though all the posts on this site for the 50 Homer, and I can only find one other post giving a serial number, and that is 7N032935 - a bike built in the same month as yours. Further searching around factory parts books has only given one further 50 Homer serial, 7T016598, as the point at which a part was modified. That, however does give us a starting point as the parts book states that it was manufactured in August 1963.
As your bike is a much higher number, this suggests yours is either February 1965 or February 1967. The 50 Homer stayed in production longer than its companion BS-7, and the 1967/8 Sales brochures still show the Homer as being available in the US. So, without a couple more intervening serial to provide some "target points", it's impossible to determine whether yours is a '65 or a '67 model.
Maybe some fellow Homer owners can provide the intervening serial numbers?
