Vintage Ralph Lauren Polo leather boat shoes

Couldn't find much info on these but have included the model number in the pictures for reference. These green and brown shoes are made in Maine USA, and according to a cobbler are made of both suede and nubuck. The left shoe has some sun damage on the sole that has caused it to yellow at some parts. The size says 8.5 but they are worn in so they may fit closer to a 9. Other than the above points these shoes are in excellent shape and look like they have many years of life left in them. Looking for a $45 value
