SIGHTS
LADDER SIGHT
The standard ladder sight is a no frills affair. It has a notch for both short and long range - no peep hole. The S and SS markings indicate scale to be used for each of two Argentine cartridges. As with all top cover mounted sights, the top cover must have a nice, snug fit for the sight to be stable, though it is doubtful that, due to vibration, any sight would be of much use once the trigger is pulled.

ANTIAIRCRAFT

Front spider sight.

The front spider and rear post sights fit in a leather pouch. The sights attatch to their respective bases using sliding dovetail joints.


Rear post sight.

Leather sight pouch.

The rear sight base, above, is a modified top cover latch, and is installed by simply removing the standard top cover latch and replacing it with this modified one.
The front sight attaches to the water jacket band, above. The projection above and to the left of the sliding dovetail joint fits around the small post that the filler plug chain attaches to, and prevents the band from rotating.
The aintiaircraft sights for the Model 1928 are extremely well made. I have found no manufacturer's markings, but the parts are stamped with matching numbers. With the bases in place, the sights can be attached in seconds.
ZEISS PANORAMIC SIGHT
The Zeiss panoramic sight was used for both direct and indirect fire. It is seen here attached to a Model 1928. The base for the sight, below, was numbered to match the sight and the gun. A panoramic sights go, this model is large and cumbersome.

At left is a link to an Adobe PDF file of the original Zeiss panoramic sight manual which has been translated to English. Special thanks to Mike Crowder (B.A.R.Gunner) for the translation. Translating technical military manuals is an exacting specialty requiring not only an understanding of the language of origin, but the principals being discussed. This manual is a great opportunity to learn how the panoramic sight is used. File size - 1.41 megabytes. Requires Adobe Reader 6.0 or higher.

This is the illuminator for the Zeiss sight. There is a small window on the Zeiss sight, just in front of the eyepiece, as seen in the photo below. There is a dovetail to allow the installation of a battery powered illuminator which provides a light source for use at night. Photo: Dave West
