OK- I am puzzled. First, the VZ33 was a Czech rifle. They are rather scarce, and have a decent collector's value IF in the original configuration. A selling price for a good to excellent specimen would run anywhere from $1500 to $2800. NOT for a sporterized version.
However, my references indicate they were made in the standard 8mm Mauser caliber (and some in 7mm Mauser) That is 8x57. The 8x63 was for Swedish troops that were machinegunners (said machine gun shot the 8x63 ammo) This was a very powerful cartridge, rifle required a muzzle brake to help tame recoil, which meant rifle could not use a bayonet. But they were not VZ33's.
In any event, you will need a hands on appraisal from someone that knows Euro firearms from that period. Sorry- wish I could be more specific.
100-400 USD
$300.00-500.00 usd
$250-$350, depending on exact model and condition.
Requires professional appraisal
Ball's book should have what you are looking for.
Yes- but the common name is 8mm Mauser.
The value of any gun is based on exact make/model, condition and originality. You have not given us enough information to answer your question. Which model of Masuer, and what condition? Value could be $50, or $500. Sorry-
Depends on the country of origin.

No published data

Can't be accurately answered in this forum. Would have to be looked at. Take it to a gunsmith.
