Indians For Guns

I have an antique beligum made 410 cal shot gun which was there with us heirloom from grandfather's time. Wondering if I can sell this especially since this one remain unregistered as no one in our family cared because of unavailability of ammos. Will this be legal to sell?

First you have to get it registered on your license .
It will come under curio if more than 50 years old .
Than you can sell it .

can u share photos plz...
