M_Boats: Strange Modified M15

I would like to know anything about the history of my recently acquired modified 1987 M15 bought from Marty Loken out of Port Townsend Wa. a few years ago . Does anybody recognize it ? It has a completely different cabin cockpit and deck shape. How is this even possible ?! I cant see any joints so I assume the entire deck/cockpit / cabin was fabricated and installed on an original hull. Sure is uglier than those original sweet cabin lines but as far as practicality goes it actually has an enviable amount of space inside. I've spent the covid year restoring her and she's sweet and sails well with the standard mast rigging and a replaced full batten main.
