Imperial Russian WW1 relic PM 1910 Maxim machine gun muzzle brake

Imperial Russian WW1 era PM-1910 Maxim machine gun muzzle brake relic. Unsure of where this was dug up originally. It is in solid condition however does have some rust visible on the inside. No significant pitting on the outside but could likely do with a proper electrolysis cleaning. Not recommend for actual use and sold only as a collectors item.
