Here is a pic I took of the serial on the transom as well as an image for the UK version of the boat.
I loved this boat and would have kept it, but could not have two boats according to the boss

This boat handled very well, and was modified from it's original format. Someone moved the headstay forward to the bow about 14' and that changed how she sailed a bit. Someone put on nice winches from a block and tackle type system for handling the sails. it has a nice spinnaker and was repainted at least once.
I looked for several years to id the boat as I was told with certainty it was an O'Day and tried to ID the O'Day as the serial made no sense when matched as an O'day. that is most likely what led me to purchasing the O'Day 26 in the long run.
After several years of digging I stumbled across the Sailcraft idea, and it turned out correct after digging up the makers of the boat and verifying with them. It was a great adventure investigating the origins of this boat.
Trying to upload the brochure as well as in PDF format. ( Wont upload maybe too large)
Hope all this helps, hope I didn't give to much away as I said it was fun investigating and discovering it all on my own. I tried finding more boat pics out there without too much luck, and the google pic is a nice one if it is this boat as it shows the pop top in action. Mine did not have canvas so I never used it, once I took it off like a Hard Top Conv and sailed that way, but the top was heavy and a bear to move to the dock.
As an aside, note the spelling of the stamp on the transom, that was unique to say the least

"MIDE IN CANADA" maybe ran short on A's
Happy sailing.
