I recently bought a minifish, serial number 001523. I bought it new when I was a kid, sold it to my sister, who later sold it to a friend. Upon the friend's passing, the boat came back to my sister, and several years later, I bought it back from her. I think I purchased it in the 1970's but not sure. Can anyone tell me what year serial number 001523 was manufactured or point me in the right direction? I can't find anything on internet. Please respond to [email protected] Many thanks in advance.
