What is the distance between frames center-to-center (from center of one frame to the center of another) and how wide the frame itself? Better in millimeters/cm since I assume the beehive itself is metric. Thanks!

I think, it is not necessary to reproduce the exact copy of the hive. There are some features, which made it unique:
- only front exposed to weather, thus - double insulation at the front;
- access to all frames simultaneously from the back;
- sliding frames;
- non-extendable design;
- beehive supposed to be the part of beehouse, thus, minimal insulation on the sides, air gap between backdoor and frames for thermoinsulation;
- screen at the back to observe the bees without disturbing.

Once these features implemented, the exact size is not such important. Many thanks Ziva for sharing all photos! Sergey
