Ad Steyr Monobloc
....WIP...
I got hold of a Steyr shotgun with these type of barrels,
could make some photos which are attached here.
I have realized that monobloc has different meanings to different people, so here are my findings.
The Steyr Monobloc barrels
. are NOT chopperlump/demibloc barrels ( as with Purdeys)
. are NOT dovetail barrels ( as with many highgrade
English or Belgian guns )
. are NOT sleeved barrels ( as with this inexpensive
barrel-repair method / by late J. Foster or Ladbroke/Langton)
. are NOT monobloc barrels ( as with a patent of H. Pieper
with the stepped seam between sleeve and barrel)
. are NOT monobloc barrels ( as with all the Perazzi guns)
They are made out of one piece of solid steel.
Barrels, barrelhook, hook for the forepart, toprib,
its one monolithic piece . No bottomrib, no soldering.
(E.Stewart has used this precise geological term in a previous
post for their product).
The gun I had at hand has Vienna proof from 1919, barrelweight
1250 g. A 16-bore, the standard calibre in central Europe
before WW II.
The contour of the barrel lengthwise is swept, the outer
barrel radius at the breech obviously larger than at the
muzzle.
So the barrelcontour is NOT that of a cone.
Steyr has been and is an industrial enterprise,
and not a lock-stock-and-barrel-shop of an artisan
gunmaker a la Ferlach or Liege.
So we speaking of an industry product and not of the
opus of a gunsmith with hammer/chisel/file.
I have told these facts to Alain, who runs this Q&A
facility in the Belgian internet forum littlegun.be.
As I am not fluent in the French termini technici,he
has kindly agreed to translate it for his collegue
Michel, the author of the book on Henri Pieper.
There is an article in the Gazette des Armes aril 2015
on this H. Pieper.
Of German origin , an engineering freak and very successful
entrepreneur,
one of the leading figures of the Liege gunmaker empire.
There are 2 tasks to clarify:
1. What has been the patent behind the productions of these
Steyr monobloc barrels. Some details point to this
H. Pieper.
2. What has been the machinery in use for it.
I am looking foreward to get an answer from the Belgian
gurus.
..
I will get access to a Steyr sidelock monobloc gun in march.
The owner told me that there more around in the vicinity
of Steyr, both in Anson- of Hammer-version.
Lets see what we can find out .
