Welcome to PugSki.com!
That isn't much to go on. Being rentals, they are NOT available retail; rental skis are specifically made for rental shops. If you are looking to get skis and boots for yourself, you would be better served shopping the retail market.
That suggestion aside, you could also call the ski shop whose sticker is on the skis. You have their ID mark: PSM161-231. They
might be able to remember that far back.
(that's a jab at rental shops and employees, not the OP)
