I've got an Arisaka great grandpa took off a dead Nazi, needs a new firing pin and spring, is it worth getting it back in firing condition?

Only other gun I own is a Single Shot Break Action 20 Gauge. Only recently accepted myself as trans, I have my first meeting about HRT on the 29th, and I feel having another gun in the house would give me peace of mind as I take on this new chapter of my life (for the first time, it feels like *my* life, and nobody is taking it from me.)
