Soviet WW2 PTRD-41 anti-tank rifle relic muzzle brake

Ground dug relic muzzle brake from a WW2 era Soviet 14.5mm PTRD-41 anti-tank rifle muzzle brake. This was originally dug up in Latvia in 2014 after which I purchased it. Came to me as a rusted lump which I cleaned to the current condition. 
 

Could likely do with a proper electrolysis cleaning but no active rust, still shows nice welding beads and grinder marks from when it was made. No visible markings present. NOT recommended for using on a live rifle and only as a collectors item. 
 

Willing to ship at buyers expense. Please PM me for any extra photos or details. Please see my other ads for similar items or send me a PM for similar inert ordnance items I may not have listed currently.
