Would need to see pics of your Hollenbeck before any evaluation could be made. The serial number would place this gun as a first year (1893) production example; and if the gun is a Grade D, that grade designation will be stamped on the water table of the frame. Early Grade D Hollenbeck/SAC guns were built to order and range in ornamentation from relatively plain to elaborate. If you can't post pics here, post that information to the forum; as I'd be willing to discuss your gun in greater detail via phone if you wish.
