Sears- jc Higgins
Savage model 87A
It will be marked on the barrel.
Made by Stevens before World War II.
No way to answer.
They were made in several calibers- will be marked on the barrel.
Should be marked on the barrel. If not, take it to a gunsmith.
The gun is a semiautomatic .22 rifle made by Mossberg. Not much of an accessory market for that gun. What are you looking for? sales@countrygunsmith.net
25-100 or so
My best estimate would be Stevens.
The L579 was a model number that was used by Sako.it describes the action type.The info that you provided will not indicate what caliber that you have.Your Sako rifle should be marked as to what caliber your rifle is chambered for,somewhere on the firearm itself.
The caliber of your Winchester should be plainly marked on the firearm.You do not say whether you have a shotgun or rifle?This may make a difference.
I just picked one up for $80
25-100 USD or so
