An "Eddystone" is properly a US Rifle, Caliber 30 of 1917. Value will depend heavily on condition, and whether it has been modified in any way. I paid $800 last year for one in very good original condition.
Mossberg made all their rifles in the USA.
Depends on the condition and age but in the region of $300 - $400
