Taking a break from posting pictures, here is some historical information:
Johann Peterlongo, Innsbruck, Tiroler Waffenfabrik Custom Steyr Mannlicher M95 Rifle 8x50R Austrian cal.
This custom Steyr Mannlicher rifle is inscribed TIROLER WAFFENFABRIK, J. PETERLONGO, INNSBRUCK on the engraved barrel rib. Johann Peterlongo was an Innsbruck Austria gun maker 1826 to 1898. Richard Mahrholdt & Son, also known as the Tiroler Waffen fabrik Peterlongo, Innsbruck, Austria was founded as Tiroler Waffenfabrik in 1854, and became Mahrholdt & Sohn in 1939. Richard Mahrholdt lived from 1878 to 1949. From 1898 to 1918 he was head of Tiroler Waffenfabrik Peterlongo Richard Mahrholdt & Sohn (Tyrol gun factory P. R. M. & son) in Innsbruck/Austria. That factory was founded by Johann Peterlongo in Innsbruck in 1854. The production of Tiroler Waffenfabrik Peterlongo R. M. & Sohn included • target rifles • rifles for high power cartridges and repeating rifles • drillings • side-by-side rifles • over-and-under rifles with different calibres • over-and-under shotguns • over-and-under rifle-shotguns • scope mounting
R. Mahrholdt was in good contact with the Suhl gunsmith August Schüler. In his time he was known as a good expert of gunnery. He is the author of the "Waffenlexikon", which was published in 1931 and its second edition in 1937. This book is even today in publication and revision.
Mahrholdt was one of the biggest gun gurus of pre-war Germany. He was also a master gunmaker with a safety drilling of his own design. His greatest legacy was the "Waffen-Lexicon", first published in 1931 followed by editions in 1937. It is still in print, but has been heavily edited so that the good info on older makers has been lost. If you can find the 2nd edition, get it. It is a treasure trove of gun lore, patents and company profiles now lost to posterity.
Mahrholdt managed the Peterlongo guns works in Innsbrück, Austria from 1898-1918 after which he took over as his own under the name of Tiroler Waffenfabrik Peterlongo, Richard Mahrholdt und Sohn. After Mahrholdt's death in 1947, it was taken over by his son, Herbert, who was also co-author of later editions of Waffen-Lexikon. The Tiroler Waffenfabrik (Tyrolean Arms Factory) closed shop some time in the 1970’s. Credit to CLUB LITTLEGUN (http://www.littlegun.be/
