A rare Breach-Loading Zimmerstutzen (Parlor Target Rifle), a product of master craftsman of the later part of the 19th century, when shooting was at its zenith the world over, and shooting champions were the superstars of the day. This particular rifle was made by Heinrich Fischer, Offenbach, Germany suburb of Frankfurt Germany. He used a recent invention of his time, the rim-fire cartridge, this one is in 6MM (slightly larger than a .22 at .24 Caliber). Shot as an in-Door, Off-Hand Target Rifle at a small target at 10 or 15 meters away.

Fluted barrel with signature top flat, butt stock made for a right handed shooter with a large checkered thumb rest. Large pivoting aperture front sight similar to a combination beach sight but with a see-through circular post instead of the small pin post for more accurate competition shooting. Usual large aperture rear sight adjustable for elevation and windgage using a large clock-key type adjustment. Metal parts were all Case Colored but now have faded to a light brown patina, with only a few traces of case colors. Metal features are finally engraved in a floral pattern. Very nice double set triggers with a fancy scroll trigger guard. Uses a Martini type drop block action with a large half moon shaped extractor. Butt plate displays an fancy acorn extension. It is also equipped with sling keepers in the narrow European style. Forearm is attached with an single engraved escutcheon.

Of Note:
Zimmer balls leave the barrel at between 800 and 1,000 f.p.s.
Built to fire either a fixed round that looks like a tiny BB cap
Hammerless breech with a slightly swamped barrel
Matted Flat ramp to front sight to minimize glare

The tiny precision round lead ball is the traditional projectile, although as seen in this picture a more modern pointed nose projectile is also available.

Checkered wrist, and perhaps some simple lines of scrollwork in the wood.
Fluted barrel on the higher grades. This is a non-essential piece of work that denotes a labor of pure love.
