I have a M65 SB, serial# ED 442. would love to know the year made and any other info you all might be able to provide, thanks for your time.
The experts should be along shortly. I would take a stab at about the end of 1969. I don't recall if they were made in 1970, but your S/N is just past the 414 shown as the last made in 1969. However, there records are not always dead accurate.
