My reference books do not list the model 815 but state that it also is the same model under the Winchester brand name made by Daisy, model 353. The model 353 is worth between $160 to $200 in excellent condition. It was not uncommon for other manufacture to make air guns under several different names and model numbers. This may be the reason the two models (815 & 353) are referenced in my catalogues
This is one of those air guns that was made under several different brand names. This model was also sold by RWS, Diana, Beeman and Hy-Score along with Winchester. I would try contacting Beeman at the link below. I believe that Beeman called it an 815T model and Diana called it a model 5.

Winchester made 2 air guns (pistols) the model 353 and 363. both are break barrel air guns. You said "Guns" so I assume you want pistols not air rifles. 1. Break the barrel down and push it all the way until it locks. 2. Load the pellet into the open breach at the barrel hinge. 3. Close the barrel back up. 4. Remove the safety. 5. Aim and fire.
This is a .177 pellet rifle.
