I have heard a few times about un-numbered Czech bolts in Turk G98 and VZ98/22 rifles. Probably the Turks bought spare parts from the Czechs. I found a perfect condition un-numbered Czech bolt in a Venezuelan FN1930 that I bet came out of a Turk rifle. I would imagine that the original VZ98/22 bolts were numbered to match the receivers.
To answer your question, yes, normal, as a replacement bolt.
