First let me state that your rifle started out as a czech vz-24,that was made for the german war effort between 1939-1942.These rifles were mostly War bring backs by vets from the second world war in europe.The most popular conversion was the 8mm-06 chambering .This was simple and economic for the gun owner and the gunsmith.It made a very good hunting rifle that could be used on most game animals in north america.Your rifle today is valued at between 250-300 dollars in most gunshops across america.
The VZ 24 PISTOL is a .380 ACP. The VZ 24 RIFLE was made in 8mm Mauser, and in 7.65 Argentine Mauser

8mm tapes can only be viewed with the aid of an 8mm player. One's best bet to watch 8mm tapes in this case is to purchase another 8mm player that is not broken.
You have a rifle which fires an 8mm cartridge, and there's a number 599 on it somewhere which may or may not be a serial number. That is all that can be derived from your question - what which 8mm cartridge it fires, not who the manufacturer is, not what model of rifle it is - the things one would need to know in order to assess the value of your rifle. So, there is no way to give an answer based on the extremely sparse information you've provided.
