It looks like an old Colt 45. See the link below.
I suggest that you go online and search for "Air gun repair" and locate a shop near you for repairs. Hahn/Crosman no longer repair this BB gun.
These guns were notorious leakers. Today Crosman owns the Hahn 45 model air pistol. Crosman offers a free service to locate shops that repair o0lder Crosman models including the hahn 45. See the link below It's also known as the Crosman model 36 frontier.
The 45 HAHN (later became the Crosman 45) in good condition (not leaking C02) would be worth between $45-$60. Mfg 1958-1970. Replica of the Colt single action Army revolver. For the owners manual see the link below

History: The PY Hahn company only made one pistol and one rifle. shortly afterwards they were bought out by Crosman air gun company. The Hahn 45 was made from 1958 to 1970. Crosman marketed it as the Crosman 45 but never changed the molds, so the pistol still said PY Hahn on its side. Most of them leaked C02 and have to be rebuilt. The rifle was made from 1958 to 1971. Repairs: If you look at the Crosman home page, scroll down to the bottom and click on "Find a repair center" if you want to have your gun repaired. Value: If you want an estimate of value, you need to give it some sort of (condition) rating like: Poor, Fair, Good, Very Good or Excellent condition. You also need to state if it is still working and holds C02 without leaking. Then I can give it an estimate of value.

The Hahn model 45 made between 1958-1970. Crosman airgun bought Hahn corp and didn't change the dies so all the Crosman model said P.Y. Hahn. In 1970 Crosman changed the model to the "Frontier 36". These bb guns were known s "Leakers" because they leaked so much C02. In good condition they are worth between $45 to $60. I own 2 of these and "Yes they both leak C02."
