Cameras produced under the name Pigeon eventually became Yashima models and Yashima then became Yashica ; this evolution is most apparent in their TLRs: Pigeonflex became Yashimaflex before morphing into YashicaFlex.
Also, the eagle-eyed among you will have spotted another Yashica connection: Tomioka was the maker of the lens. It is a 4.5cm f3.5 S-Lausar triplet and is the less expensive version of Tomioka's offerings for the Pigeon range, the Tri-Lausar being the better lens; but the S-Lausar is no slouch. The camera has a NKS shutter with speeds from B, 1/10s to a maximum speed of 1/200s. It offers double-exposure prevention as well as in-built flash-sync.
