Excellent rifle Huvius in a great calibre - especially as at a good price!

It looks very much to me like a W&C Scott or Philip Webley, both made quality rifles for several of the top retailers, the percussion style fences is frequently found on both makers guns/rifles, as well as the lever fore end release

The medium height hammers and rebounding locks possibly 1880s?

There is a clear space for retailer/maker's name, maybe made on spec? Style and calibre would find a ready market

Good luck shooting it and please give us a report
