For more details on manufacturers/provenance, see description below.Possible gunsmiths / places of origin (likely candidates)Belgium / Liège (factories & contract manufacturers) — barrel manufacturing or proof very plausible. (ELG).Netherlands — P. Stevens (Maastricht), Dutch arsenals / manufacturers — strong link to Beaumont system.German gunsmiths (modification/fine work): Suhl / Zella-Mehlis, Ferlach (Austria) and regional master workshops in southern Germany — these regions are known for quality modifications/refinements to shooting/hunting rifles. (Based on stock shape, trigger, artisanal adjustments).Individual gunsmiths (custom-made) — Since the stock, chamber handle, and details are modified, much points to a bespoke German/Austrian workshop work around 1890–1930. Dating (original parts vs. modification)Original parts (Beaumont basis): 1871–1885 (production / series production) — corresponds to the normal production period for Beaumont rifles.Modification / conversion to civilian shooting rifle: typical modification period approx. 1890–1930 Re-proofs often occur in the 1930s during repair/modification – repair proof marks Other technical detail (from your information)Barrel: octagonal, length ≈ 60 cm (typical for target rifle / precision setups).Lock: closure nut with side locking — important distinguishing feature; may indicate specific workshop modification or reprofiling of an original lock.Chamber handle: modified — typical for subsequent ergonomic adjustments. Price expectation / negotiation basis: VB (on request); realistic comparison prices for Beaumont pieces in 11.3×50R / 11×52R typically range between €300–€1,200 depending on original condition and completeness (reference: international auction sales from recent years).The sale is made as a collector's item.
