These are all the original first batches of the Japanese made FA Limited lenses, note the different coloured genuine leather pouches and a different lens cap printing of the Pentax logo for the 43 Limited.
Btw, that Pentax guy has quite some exotic Pentax film glass, like FA*300/2.8 and FA*400/5.6 as well as the rare FA*200/4. But those were the days when Pentax still made and marketed those higher grade glass with better specifications.
