It is difficult to tell when information is covered up. The booklet seems a later variety for three early-war BMs, which although possible, would probably have included other awards if filled out post-war.
Three pentagonal-suspension awardings of BMs to a single recipient are a truly rare occurence, however three early-suspension BMs would be even rarer - I've never seen such a group.
It could be good, but at face value I'd be skeptical.
I just realized that there are two BM and one CSM, but I still am skeptical.
What you see on the scan is Medal Document - Type 2 (by Mondvor site classification). Type 2 documents were issued from 1947.
In addition, I see signature of Pegov, which started to appear from 1953.
So, the Order Book was issued on or after 1953.
First entry in the book is Medal For Military Merit with SN below 100,000, which probably was awarded in the beginning years of Patriotic War or even pre-war.
Why do we have order book for such early awards issued only after 1953?
Yes, it would be possible, if the recipient lost the original book for instance. Now, you want to have a look at the very bottom of the page, under the medals. There is written the date the booklet was issued.
Ruiz I'm afraid only research could confirm or decline it, Entries in booklet look OK, but those are so easy to fake, bear in mind there were hundreds of stamps left at military commissariats, most of them got sold to different kind of people.
