Baikal Makarov Serial Numbers
This might help some: Then compare to pictures here for a general format by country: Remember, Bulgie surplus dates are the first two numbers +60 and the EGs are dated by year 58 to 65. If you run across a way to date IJ-70s (sans manual) and Chinese type 59 ZZs by the serial number, please let me know. Using advanced search on GunBoards can give one a virtual plethora of info to glean from.:thumbsup. :) Serial # prefixes, generally considered lot codes, don't get a lot of discussion because the commies kept production numbers to themselves. The East Germans kept good records, but the published list for EG Mak prefixes is incomplete, as examples show up not listed. Without representing a number of guns produced in that lot; and the year of manufacture marked on the weapon, the prefixes are just 'there'. Cyrillic is cool to see on some examples, but I don't know what it means on a Makarov, so my brain just falls asleep.

Note that this table is not complete and there appears to be a sequential pattern, so don't panic if yours doesn't fit into the ones listed.

East German Makarov: A Cold War Classic. By Cameron S. White - Friday. The Makarov Is Born. A range of serial numbers has been observed across the various letter codes for the years 1960.
Not many are available, so they often command a premium over other Makarovs. On the whole, the quality of these is not as good as some of the others, but there have been notable exceptions. Very rarely you may run across a Type 59 with an Arsenal mark (number) in a triangle. Most common found are 56 and 66. These were Military pistols that were remarked and packed for Commercial Export.
A Chinese Makarov with 'SHI' mark is of Military issue, and normally if found in the USA means it was a War Trophy 'bring Back' from some conflict, and commands a Premium price. Bulgaria The Bulgarian Arsenal Makarovs are the only ones that are currently being imported into the country. Miltex had an exclusivity agreement with Arsenal before they decided to get out of the small arms business. 
Many other Bulgarian Makarovs are out on the market including some military surplus. As the Bulgarians start to switch to other guns as standard police and military issue, these should continue to pop up everywhere and can be purchased at a very good price. Fortunately for US shooters, these are very nicely done and some interesting variants were delivered by Miltex.
