Sheridan Products. Sheridan Products Inc. was an American air gun manufacturing company. It was purchased by the Benjamin Air Rifle Company in 1977, and later purchased by Crosman in 1994.

Company history
Sheridan Products Inc. was formed to produce Pneumatic Air Pellet Rifles  with production beginning in March 1947. In the early 1940s Co-founder Ed Wackerhagen, dissatisfied with a pellet gun used by his son, set out to build one of the finest airguns in history. The design was to incorporate the philosophy: "Performance is the sum total of many small functions whose combined result must spell 'Bulls-eye'". It was to be called the Model A, also known as the "Super Grade". This air gun was to fill the gap between the "BB" gun and the .22 caliber. A successful prototype was produced mid-1944 and in 1945, in partnership with I.R. "Bob" Kraus, Sheridan Products Inc. was born in Racine, Wisconsin. The name Sheridan was reputedly in honor of the Civil War's General Philip Sheridan.

The Sheridan Model A "Super Grade" was introduced in 1947 and is considered one of the finest air rifles ever produced. Unfortunately its high cost (MSRP $56.50), translated to very slow sales. Within a year, it was decided that a cheaper model was needed, and in 1948 the Model B "Sporter" was born. Designed to be less expensive than the Model A, it had a MSRP of $35 when introduced. Apparently the price point of the Model B was still too high, and sales continue to be slow on both rifles, which was of great concern to the newly formed Sheridan Company. It was quickly realized that for the company to survive, a much cheaper to produce model must be designed. This philosophy gave rise to the last Sheridan model, the Model C "Streak" introduced in 1949. Its MSRP at introduction was $19.95 and was selling for $23.95 by 1950. This is the model that ushered Sheridan Products Inc. into profitability. The Model C Silver and Blue Streaks are the pellet rifles that Sheridan is primarily known for, since the Model A's and B's are relatively scarce. Sheridan manufactured the Model C Streaks for 27 years before being bought out by the Benjamin Air Rifle company and ending the original run of Sheridan produce Streaks. Many small changes were made to the Streaks during its 27-year run, providing collectors many different varieties.

Sheridan was purchased by the Benjamin Air Rifle Company in 1977.  That company was later purchased by Crosman in 1994.

Products
All Sheridan air rifles Model A, B, and C are multi-pump, single shot, bolt action, breech-loading, and .20 (5mm) caliber. Muzzle velocity figures are for Sheridan's standard weight pellets of 14.3 grains.)

Model A (Super) (1947–1953) Total Production: 2130 Velocity: Variable to 700 fps. With a large cast and machined aluminum receiver, bronzed barrel and pump tube, walnut stock with Monte Carlo cheek-piece, ball-type valve mechanism, adjustable trigger, and peep sight. It weighed 5 pounds 14 ounces, stretched 37 inches overall, with a 20-inch barrel with one turn in 12 inches.  MSRP $56.50.

Model B (Sporter) (1948–1951) Total Production: 1051  Velocity: Variable to 700 fps Designed to be less expensive than the Model A (Super) Using the same gun, but without the cheek-piece, a revision of soldered ventilated rib type barrel, less expensive paint finish and various slight changes it was to be a cheaper alternative to the slow selling Model A. MSRP $35 when introduced, $42.50 when production stopped.

Model C (Streak) (1949–1976) Total Production: Unknown. Velocity: Variable to 700 fps. Designed to be less costly to produce than the Model A (Super) and the Model B (Sporter).  Although less costly to produce when compared to the Super and Sporter Grade, the Model C were still well constructed Airguns using quality materials. They  utilized walnut stocks, aluminum receiver, bronze barrel and pump tube. A different valve mechanism was used in the Model C than in the previous Model A and B. It was dubbed the "Streaks" with the Silver Streak being first with its Nickel finish, followed by Blue Streak in a black oxide finish  in 1952. The only difference between the two Streaks is the finish. MSRP 19.95 at introduction and was soon selling for $23.95 (1949–50).  
Sheridan Products Inc was acquired by its competitor, the Benjamin Air Rifle Company in 1977, thus ending the original line of Sheridan Model C's in 1976.* 
(Benjamin Air Rifle Company continued producing Model C's until 1992 when the company was purchased by competitor Crosman Corporation. Changes to the design of the Model C were made by both Benjamin and Crosman.)

Model F (1975-1990) Total Production: Unknown. Velocity: Approx. 500fps. 5mm or .20 caliber, single shot, bolt action.
     Though very similar to the Model C, the Model F is powered via CO2. With a Walnut stock and rocker-type thumb safety, this airgun is a great collector's rifle, known for its accuracy. As previously noted, in 1977 Sheridan Products Inc. was acquired by the Benjamin Air Rifle Co., also ending line of original Sheridan Model F's in 1976.

Dating a Vintage Sheridan Model C (Streak) 1949 - 1976
(be aware that changes often cannot be pinpointed exactly, so most changes will only be list by year they first appeared) Date stamps on 1964 to 1971 and serial numbers on 1972- 1985 easily pinpoint manufacture dates for these years. This change chronology is most useful for identifying approximate manufacture dates for Model C "Streaks" produced from 1949 to 1963, the "Thumb Safety" version of the Model C Streaks.
