Serial Number Table Last Edited: 05/14/17 03:32
NOTE: dates shown are JAN 1 unless noted, so the serial number shown is the *first* serial number produced the given year. Exceptions are serial
numbers preceded by "up to"(where you can assume that the numbers reported in that subsection are DECEMBER 31, END OF YEAR NUMBERS)
or rows where a month is given in the month column. If the serial number is shown as a range (xxxx-xxxx) it indicates
that we know the entire range of serial numbers for the given year.

Platen Diameter |
Moskva 3 and 4 have factory platen diameter of 32mm. Exact data for Moskva 2 is unavailable (likely 32mm or 32.3mm). Moskva 5, 6 and 7 have factory platen diameter of 32mm. Moskva 8M (and likely 8) have factory platen diameter of 32.3mm. |

Model 1 | |||||
1 | 1937 | Model 1 started in 1937, as a prototype of machine that quickly became the Model 2. It never entered production. | 64 | ||
Model 2 |
Model 2 was produced between 1938 to 1951. Its design is generally based on the
1931 Underwood Standard 4-Bank Portable. Pre-war edition features embossed logo and two decals on lid. Post-war edition has a red enamel badge on the left side of the lid instead of decals, though an embossed logo on the paper table is replaced with decal. Presumably, there were less then 39000 made (including both pre-war and post-war versions) with the highest yet known serial number 38295. |
64 | |||
1 | 1938 | Model 2 (first version) begins at serial #1 in 1938. Model 2 (second version) begins before serial #17,674. | 64 | ||
1941 | Production halted during WWII. The highest known number for the pre-war series is 9819. The next known machine is 17674, from the post-war series. |
64 | |||
1946 |
Production resumed?
Actual production resumption might have happened early 1947 instead of 1946. |

29850-38295+ | 1951 | Approximation. Numbering for the models 2 and 3 during transition may be quite tricky. Numbers are possibly scattered, both in terms of models and production dates. For instance, Moskva 2 No. 38295 has an unexpectedly high serial number for 1951. This fact leads to a speculation that a small batch of Moskva 3s with lower numbers might have been produced in 1951. | 64 | ||
Model 3 |
Model 3 started in 1951 and ended in 1955.
Its production is estimated as approx. 35000 machines. It was succeeded by Model 4.
Both models share the same body style (which is an obvious copy of the 1938 Underwood Universal),
but have different segments and ribbon vibrators. |
64 | |||
Prototype | 1950 | Already existed in July, 1950. | 64 | ||
<39000 | 1951 | Approximation. Numbering for the models 2 and 3 during transition may be quite tricky. Numbers are possibly scattered, both in terms of models and production dates. For instance, Moskva 2 No. 38295 has an unexpectedly high serial number for 1951. This fact leads to a speculation that a small batch of Moskva 3s with lower numbers might have been produced in 1951. | 64 | ||

55000 | 1954 | Approximation. | 64 | ||
65000-68154+ | 1955 | Approximation. Produced concurrently with model 4 for some time. | 64 | ||
Model 4 | |||||
1 to 2033-4 | 1955 | 05 | Approximation. Production probably begins in May, 1955. Lower 1955 numbers are extended with a postfix "4". The highest yet known is 2033-4. |

53300 | 1960 | Approximation. | 64 | ||
64400-67655+ | 1961 | Approximation. The latest documented Model 4 is from the late 1961, but it is possible that production continued into early 1962. There were about 68000 made. | 64 | ||
Model 5,6,7 |
Models 5/6/7 started in 1959 and ended in 1972.
Their body style slightly similar to Smith-Corona Super 5.
Most of the series have detachable carriages.
Moskva 5 may have detachable carriage without case springs adjusters
(as well as the carriage may not detach at all).
Models 6 and 7 both have detachable standard (6) or wide (7) carriage
and case springs adjusters below carriage locks.
About 1963, ring keys were replaced with plastic keys
(though, for some time [1963-1964?] production ran concurrently).
Also, "Model" was gradually replaced with "M-" since then,
but did not affect Moskva 5, which could have been out of production by that time.
M-7 was also discontinued earlier than M-6, possibly about 1969.
Final edition of M-6 lacked detachable carriage (due to unification with M-8?). There were more than 400000 Moskva 5, 6 and 7 made, including the early 5s. |
64 | |||
1 | 1959 | Approximation. Models 5, 6 and 7 (1959–1972) share the same number sequence. 5 was an early model, introduced in 1959, 6 and 7 followed it in 1960. Numbering deviations are quite common, since prefabricated and already numbered frames were supplied not in order to the assembly line. Scattered numbers make precise approximation virtually impossible. There is always a place for a minimal error at 100–150 units. | 64 | ||
24000 | 1960 | 64 | |||
46500 | 1961 | Approximation. 1961, 1964, 1969 and 1970 approximations are slightly more rough than others, while 1963 and 1965 are believed to be quite close. | 64 | ||

Model 8/8M | Model 8 started (presumably) in 1969, but it was replaced with a modernised version called 8M
(or M-8-M) in 1972. The former model was built to the 1957 National Standard
(ГОСТ 8274-57),
while the latter one follows the 1971 standard (ГОСТ 8274-71)
It is assumed that M-8 was produced in plastic body in 1969-71,
in metal body (possibly) in 1971-72 and then replaced with 8M without new serial numbering.
Plastic M-8 is the only Moskva portable to support dual-coloured ribbons. Production of 8M continued into 1983 and in the last production years model index changed to ПП-215-8M instead of usual 8M. A new model (built to ГОСТ 8274-57)of the Ortekh brand was a successor to it since 1983. Finally, the last Ortekh rolled off assembly line about 1995. |
64 | |||
Up to 50000 | 1970 to 1971 | Approximation. Model 8 started (approx.) in 1970, but was replaced with model 8M very soon, likely in 1971. | 64 | ||
