The extensive chapter on the Vz. 52 has to be one of the most complicated read on a pistol and serialization scheme. The author notes that it was meant to trick the West into overestimating the output and military strength of the armed forces. Suffice to say, a block serial scheme, skipped lettered prefixes, staggered number ranges, etc. created the illusion of much larger output than actually done. Supposedly, standard production ended in 1954 but leftover pistols were not completed and dated until 1955. The author's (James D. Brown) table on production by year and series merely states under 1955, "unspecified" and estimates 320 pistols left over from 1954 series production. My head hurts!
Tiberian - photos of your Vz.52 would be nice.
LittleJenny - would love to see photos of your pre-B on another thread.
