Basically the M24/47 is a rework of the M24s that Yugoslavian purchased/produced before WWII. The did some slight updates, refurbished them, replaced any worn out parts, scrubbed all the monarchs markings (though you may find some), and then threw them into storage. One important thing to know about the Yugoslavian M24/47 is it is a intermediate Mauser action, which means it is slightly shorter than the standard K98/G98 action.
Value is in the 350-500 area depending on who is interested. The value might to up a little if you have the proper bayonet and if you have other accessories (cleaning kit, frog and scabbard, sling etc.).
