Allen’s 32RF Side-Hammer Revolvers

Allen’s 32RF Side-Hammer Revolvers
  • Production period:

    From 1858 to 1863 during the Allen & Wheelock era, and later from 1869—when production resumed under E. Allen & Co.—through 1871.

  • Production quantity:

    The First model has been manufactured in limited quantities. However, based on the number of surviving examples of later versions, we can confidently say that these were manufactured in substantial quantities, likely exceeding 3,000 units for the Second model and even 5000 for the Third model. On the contrary, the Third model brass frames are extremely scarce.

Production of the side-hammer 32RF revolvers began shortly after the introduction of the 22RF models. Aside from their larger size, the .32 revolvers closely mirror the .22 versions in overall design with the characteristic side-mounted hammer on the frame.

These revolvers typically have a six-shot capacity in .32 Short. As with the .22 rimfire models, users had to remove the cylinder for loading and unloading, using the cylinder pin to eject spent cartridges. Later in production, Allen introduced also a variant with a longer cylinder to accommodate the .32 Long cartridge.

Production halted in November 1863 due to a patent infringement lawsuit but resumed in 1869 during the E. Allen & Co. period after the Rollin White patent expired.

The revolvers were standard finished with blued steel frames, cylinders, and octagonal barrels measuring three, four, or five inches in length. Toward the end of production, the company produced limited numbers with brass frames, which are now considered rare. Walnut grips came standard.

Early models featured finely scroll-engraved cylinders depicting a country scene of dogs chasing a rabbit. In later production, the engraving was omitted.

Variations

Three primary variations of the revolver can be identified. The following overview outlines the distinguishing characteristics of each model.

 

First model with its characteristic pinscrew

First Model: This version has a cylinder pin secured by a setscrew located at the bottom of the frame. It is equipped with a ‘quick drop’ style grip, characterized by an almost straight grip angle. The hammer-face is fully rounded, and the recoil shield is notably thick. Early first-model variants have a cylinder length of 0.905 inches, while later examples measure 0.940 inches.

Late production second model without cylinder engraving and a fully square hammer face

Second model: Starting with this version, the cylinder pin is retained by a spring-loaded latch. This model can be found with various hammer types, including fully rounded, half-round/half-square, and fully square hammer-faces. The recoil shield is thinner and more rounded in profile. Early examples retain the cylinder engraving, while it was omitted in later production.

Midway through production of the Second Model, a patent date marking of July 3, 1860, was added to the side of the frame.

This patent referred to the raised portion of the recoil shield, designed to prevent the cylinder from jamming due to expanded cartridge cases after firing. This raised feature had already been implemented on most First Models, however without mentioning the patent date on the frame like we see on the Second and Third Models.

Third model: This version features a redesigned, more elegant frame with a ‘slow drop’ grip, similar to that found on contemporary Smith & Wesson revolvers. Only the fully square hammer face is encountered on these models.

The revolver was available with a 0.94-inch cylinder for the .32 Short cartridge, or with a 1.2-inch cylinder for the more powerful .32 Long cartridge. Barrel and frame markings are identical to those of the second model.

Toward the end of the production period, a limited number of revolvers with brass frames were also manufactured, in both short and long cylinder configurations.

Forth model:

Following the forced halt in production in 1863, manufacturing resumed in 1869 under Ethan Allen & Co. Apart from updated barrel markings and the adoption of a blade-style front sight, these revolvers are essentially a continuation of the third model.

Allen’s Side-Hammer Lipfire Revolvers

Allen's side-hammer lipfire revolvers are scarce six-shot pocket revolvers produced primarily between 1861 and 1863 in .32 lipfire caliber, with limited production resuming after 1868. They are distinguished by their side-mounted hammer and innovative overhead rack-and-pinion ejector system, a unique feature among Civil War-era handguns.

An overview of Allen's six-shot .22 Rimfire side-hammer revolvers, which share the same basic design as the .32 Rimfire side-hammer models, including the distinctive side-mounted hammer and solid-frame construction. The .22 Rimfire revolvers were produced in eight versions, each incorporating variations in design and mechanical features.
