Very nice looking rifle you have there; my "B"-block Vz.98/22s is just 197 rifles ahead of yours. I'd guess yours probably picked up the Germanicon bolt in Turkeyicon, or during importation to the USAicon.

The Czechoslovak Govt. only got 1,500 rifles from Mauser Oberndorf as reparations via treaty; the spare parts and manufacturing tooling they purchased from Mauser Werke in 1920. The first approx. 10,000 rifles manufactured at CZ-Brno were 99% copies of the post-1916 Gew.98; only the grasping grooves were omitted. These rifles were designated Vz.98. Shortly after production began, it was decided to use the Mauser-patent tangent-leaf rear sight in place of the Lange-Vizier. The new rifles were designated Vz.98/22, and were produced in 10K blocks prefixed "A"-"D", with the switch to the shorter Vz.23 coming mid-way through "D" block.

In 1926-27 the Republic of Turkey purchased 30,000 Vz.98s and 98/22s, and placed an order for 10,000 new 98/22s, which formed a special "E" block.
