Do a google search for JC Higgins Model 29 and you will find a downloadable PDF file for the original owners manual. That is where I got mine and yes, it is the original owners manual.

Contact S&W for an owners manual. Too long to reproduce here.
I only have some information for you. Any JC Higgins air pistol that begins with model 126 was made by Crosman air gun. Any model that starts with 799 was made by Daisy air gun. I suggest you click the Crosman link below and check the owners manuals to try to locate your pistol. Then re-post the Crosman model number along with the condition of the pistol to get an estimate of value.

The JC Higgins Model 20 was a slide-action shotgun, not a pistol. Is that the gun you have? sales@countrygunsmith.net
