>>last week I had the pleasure to inspect a hammer double rifle with an underlever opener to the right hand side. It is marked on one side plate with "Joh. Springer´s Erben in Wien"
and on the other side plate "K. u. K. Hammer Gewehr Lieferanten" = royal hammer rifle manufacturer

It is very elaborate in embellishment and has a small stock plate silver? with a crown.
The functioning and fitting is very good, there are also some time-consuming details in the making:
front post and rear sight are in a matching blue color from heat treatment, there is a small diopter post inlay on the upper wrist side, all screws are decorated with embellishment, and the visible screw slots are in line, etc.

The barrels are of 64cm length and have on the flats the serial no. 91xx and proof marks of austria (eagle and shield with a cross).

There is another number also on the flats, which might correspond (partly) to the barrel diameter:
1150.01

Directly on one barrel, not on the flats, there is one number stamped: 24.01.11 .4
which might be a production date of the barrels and the 4 ? I do not know.

The rifle has a shallow profile in the twist which would match the use of lead bullets.

There was no other information or paperwork connected, only one box of ammunition by the manufacturer
"Dorfner, Wien" with the caliber designation ".450 Express / 60 ",
which seems a little bit odd, because
- if the rifle was a .450 Black Powder Express, the case should measure 3 1/4" in length,
but the measurement on the ammunition case is 60mm case length.
- the light weight of the rifle = 3050 grams 6 1/2 lbs indicates a stalking rifle for small game like roe deer, which does not need the power of a full .450 BP Express.

If anyboday can bring more information about the cartridge or other interesting details I would be very delighted!<<

From the serial number from 1901 it sounds like it was sourced from a maker other than Springer's Erben.

Post by Axel E. referencing Dixon:

>>The 11.6x60 R aka 450 Short was not uncommon in central Europe, especially in the realms of the Austro-Hungarian empire. As the cases have the 14 mm base of the British .450, cases for the American .45-90 are much too thin for reforming. Nearly ideal would be RWS cases for the old 10.3 x 60 R aka .450-400 2 3/8” BPE.
