Pentax Serial Number Database
I just bought a beat-up old K1000 SE that is all metal, has the AOCo on the pentaprism and the serial number starts 637****. It has no reference that I can find anywhere as to where it was manufactured.
Asahi Pentax S came almost a year after the original. The only significant improvement was the shutter speeds changing from 500-200-100-50-25-10-5-2-1 to the more mathematically correct 500-250-125-60-30-15-8-4-2-1, as had become more common at the time. Besides, the inner base and right side wall was prepared for the actuator that was to come with the K model two months later. These differences is described later. Another small change was the design of ASA values on the dial around the rewind crank. The AP had ASA engraved on the top plate of the body, while the S had it written on the ASA dial.
The whole range of pre-Spotmatic PP SLRs has been named the S-series. My first S model camera has sn. Best adobe acrobat x pro crack amtlib dll 2016 free software. Size: 145x92x50mm. Weight: 580 g.

Asahi Pentax K, some sources say for King, others say Kilo (1000, referring to the shutter speed) was released less than two months after the S, and was Asahis first with a shutter speed of 1/1000 sec. But more important was the new set of lenses that came with it, the Auto-Takumars, giving you a semiautomatic diaphragm. When pushing the trigger,the aperture of the lenses were set by a pin that was pressed by a moving part, an actuator, just inside the mount of the camera.

Asahi Optical had really shown the way forward for the camera industry with their first three PP SLRs from 1957 till 1958. Already in 1959 they continued their S series with the S2.
The whole series was a continuing development, sometimes with different versions of the same model, other times introducing new models. There were at least two versions of the S2, the later one with a notch in the shutter time dial to fit the new light meter introduced in 1960. In addition to this, the S2 had different names for different markets. The Asahi Pentax S2 for Japan and general international market, Asahi Pentax H2 sold in several markets, Honeywell Heiland Pentax H2 sold in the US, later branded Honeywell Pentax H2, Asahi Pentax SB, B instead of 2, being the second letter in the alphabet,sold only in Japanese military camps, (from 1961 also the very rare SB2, a special version of the S3) and Asahiflex H2 sold in South Africa, possibly also in Finland. However, although not mentioned in literature, there was even an Asahi Pentar H2 AND a Penta Asahiflex H2 produced for the South African market, maybe also sold elsewhere.
