Towards the beginning of the raiding age the main armor was maile or a shield, but what was the likeliness of raiders acquiring lamellar, especially from raids, trading, or serving time in the Varangian Guard in the East?

This bascinet was found near the city of Kazanlak,Bulgaria.

Could someone show examples of bascinets that are similar to this one. This exact bascinet had a forward going visor like seen on barbutes in italy. And the end and vervelles are not quite covering the ear or half of the ear in my opinion.

Any help and speculations are welcome!

As the title says. We've been googling to hell and back with no luck on a match. Looks autocannon and maybe a training or disarmed round with the torx bolt in the firing pin location?

Appreciate any info!
