Can't be answered without a detailed description of ALL markings.
J.P. Sauer & Sons of Eckernforde, Germany made all, to my knowledge, of the various firearms imported and sold by Hawes Firearm Co. of Van Nuys, Ca. I believe that Hawes Firearms was in and out of business in the 1960,s. I, by the way, have a couple of their single action revolvers and find them to be very good guns. My belief is that they are probably about as strong as a Ruger. J.P. Sauer & Sons only made cartridge firearms. The Hawes Firearms replica black powder percussion revolvers were made in Italy by Arimi San Paolo, Rigarmi, and another unknown Italian manufacturer using COM marking. Some were marked just "Made in Italy" along with the Hawes Firearms markings. Dr. Jim L. Davis

Revolvers are not taken apart except for repair. Suggest you find a gunsmith. Instructions far too lengthy for a Wiki Answer.
Hawes imported inexpensive black-powder Italian reproductions, so the value is not going to be high. Doubtful the grips are actually ivory. sales@countrygunsmith.net *go to Bluebooks Publications, Inc...Firearms...bottom of page offers appraisals for $20.00/2% if above $500.00.

Hawes was an importer of replica percussion revolvers. The brass frame .36cal. with an unengraved cylinder is actually a replica Confederate Schneider & Glassick. There are only three original Schneider & Glassick revolvers known to exist. Value of the Hawes replica Schneider & Glassick would be $200-$300.
