No, they are not. Most of the dates are when the aircraft was received from Germany, some of repair or overhaul and some of the 100 % loss or minor crash.
If you are interested in operation of Bf 109 G-2, G-6 and G-8 aircraft in Finland, I recommend the following book:
"MERSU, Messerschmitt Bf 109 G Suomen ilmavoimissa" by Kari Stenman and published by Koala-kustannus. ISBN 978-952-229-188-2. 400 pages, 485 photos and 56 drawings.
See:
http://www.koalakustannus.fi/kirjat/...php?id_prd=233
It contains full history of the Bf 109 operation in Finland from 1943 till 1954. There are details of every one of 162 aircraft flown by the FiAF, full list of claims etc. Engine numbers are however missing.
Unfortunately this book is in Finnish, but using Google translator it should be fairly easy to find the most important and interesting details.
