Manufactured circa 1847 to 1865. Marked "ALLEN THURBER & CO WORCHESTER" on one barrel flute, "ALLEN'S PATENT / 1845" on the left side of the hammer and light floral scroll engraving on the frame and nipple shield. Matching serial number on the frame under the grips and stamped on the inside of each grip panel. Fitted with smooth varnished walnut bag shaped grips.

Good. The metal surfaces have been cleaned bright with scattered minor pitting. The grips are good retaining most of the varnish and having a few scattered minor nicks, dings and handling marks. The trigger has to be pushed back into the ready position after firing, otherwise the action functions properly. The markings and engraving remain clear. From the Will Hoffeld collection, purchased from Ron Reterson in 1989.

Marked "STOCKING & CO. WORCESTER" on one rib, "WARRANTED CAST-STEEL" on the next. The Springfield eagle head proof follows this last marking. The left side of the hammer is marked "PATENT SECURED 1848". No nipple shield and removable nipples (one missing). This variation is considered rare in these pistols. Fitted with two piece bag shaped walnut grips.

Good. The metal surfaces have a brown patina on the barrels and gray elsewhere with scattered minor pitting. The grips are good with heavy pitting on the right side escutcheon, some minor marring on the bottoms, a few minor dings and a hand rubbed finish. The action needs work an done percussion nipple is missing. The markings and engraving are clear. From the Will Hoffeld Collection, purchased from Donald Pansch in 1998.
