1945 SARAJEVO, overprint

There is not much known about overprint process, how many plates they had, what are the positions of some overprint characteristics, etc. Generally, we know that two types of overprints exists: type I with normal coat of arms and type II with broken coat of arms. Type I is rarer!

After a quick analysis of my blocks I found that all belongs to the same positions on sheet. All blocks have both types, good and damaged star as well as other overprint characteristics shown below.
