SM 1 Portable   Olympia SM 1, 2, 3, 4, 5 & 7 Service & Repair Manual Printed Book | PDF
12300-30000 1949 Model SM-1 begins: The keys are black and circular, except for the function keys which are dark green and have a tombstone shape. Colors offered include black, green, dark red, and cream.

SM 2,3,4,5,7,8,9 Portable
69390-99000 1950 Model SM-2 begins: new keytops and new styling, although the machine inside is largely the same as the SM1 at this time. The keytops are usually black, though sometimes with dark green function keys. Crinkle finish colors include olive green, black, and dark red.
30,24,121
99001-206000 1951 After serial number 170000, the keytops, now with cushioning, are flipped 180 degrees to resemble the more common 1950s Olympia keys, though the function keys remain the same, and body pieces changed slightly although the styling remained the same. The Olympia logo is now moved to the ribbon cover. The SM2 still has no tabulator and the margin sets are hidden behind the paper table. There is a new return lever.
30,121
206001-304000 1952   30
304001-430000 1953 Model SM-3 begins: SM3 has a tabulator with manual stops. The margin sets are moved to the top of the carriage with the tab stops under on the back. It usually has De Luxe written on the segment.
The first version of the SM3 was produced only for a short time in 1953 and possibly early 1954. It has the smaller shift key of the 1952 SM2 and slightly different plastic card holders angled to fit around the wire card holder.
30,121
430001-590000 1954 Again, somewhere around serial number 500000 in 1954, another change, though slight. The shift keys become larger. SM3 gets different plastic card holders

924301-1109075 1957   6,30
1109076-1333915 1958 Model SM-4 begins: This was an improved version of the SM3 with a keyset tabulator.
These were produced in a number of colors until 1961, ending when the SM3 ended. Most have a squared-off case with grey and white stripes, although some have the silver streamlined case.
6,30,121
1333916-1524842 1959   6,30
1524843-1731684 1960 Model Monica begins: a stripped-down model that began in 1960 and continued until the end of Olympia production in Germany, spanning a number of body styles. The first Monica was similar to the SM2, but without a chrome stripe around the base of the machine, with different, simpler rubber feet, and less liberal use of chrome finishing. The eraser table is also lacking.
All Monicas have an eggshell or textured glossy finish in an off-white color.
6,30,121
1731685-1949309 1961 Model SM-7 begins: much the same as the SM4 inside, having a keyset tabulator, but with a modernized angular body. It was produced in 3 colors; white, pink, and blue. Some have a "Made in Western Germany" badge below the Olympia logo but most don't.
The SM7s with pink or blue bodies as a rule have all-white keys and knobs, while the white-painted ones have turquoise shift keys and knobs. They all have a squared-off case with grey and white stripes.
Model SM-5 begins: Introduced at the same time as the SM7, the SM5 was a less-expensive option. It's like a cross between an SM2 and an SM3, having the SM2 style paper table, but with a manual-set tabulator. It was produced in just one variation.

2194889-2414048 1963   6,30
2414049-2636380 1964 Models SM-8 and SM-9 begin: introduced in 1964 with an all-new segment shift design and a new body. The keys were off-white with turquoise accents. The logo was originally turquoise as well, but this changed to a chromed part in 1965. Painted Dark Gray on bottom shell and carriage paper table, Off-White top shell.
The SM8 is an SM9 without the keyset tabulator and touch selector. It also has body-colored carriage ends, rather than chromed as with the SM9.

2918569-3222680 1966   6,30
3222681-3433391 1967 SM-8 and SM-9 paint is changed to Slate Gray bottom shell and carriage paper table, Pearl Gray top shell - after Serial #3,391,065 - Olympia called this "Step 1 Color". Turquoise plastic parts are retained until Serial #3,447,700, in 1968, when they are changed to Dark Gray. 6,30,159
3433392-3630903 1968     After Serial # 3,533,565, the color of the bottom shell was changed to Slate Gray, while the top shell changed to Saturn White. The previously Turquoise plastic parts like the shift keys had changed to Dark Gray after serial #3,447,700, and the rest of the keyboard and the carriage knobs changed to Slate Gray after serial # 3,533,565. The carriage return lever now is able to fold down to fit the new smaller black plastic case. 6,30,122, 159
3630904-3941129 1969 In 1969, a similar but completely new body shell was introduced along with moving the tab set keys from the sides of the spacebar to the left of the keyboard. The white paint was also brightened. The touch selector was moved from there to under the ribbon cover. This marks the introduction of the new all-caps Olympia logo.
