Just saw that the pix have been added. It is, indeed, a Compound shutter, and on a Tech III board. Looks identical to mine. As I wrote, I have only used mine with a monopod, not plain-ol' hand held.
My serials are 3415525 lens, and 757876 shutter. My Tech III version four kit means that my serials should be c. 1954 (just like my Speed, and my other Technika, entirely coincidentally), so I assume yours is early '50's or maybe late '40s. I assume it came on a Tech III version one, two, or three.
