Rick/David,
My understanding of the Observers/Gunners seat is that it went through several evolutions during the development of the the Lynx. The seat that you have Rick is the first version and the second drawing is of the later version. I was able to replicate the raising/lower mechanism, but the seat base pan and back was too much of a challenge. I elected to use the Driver's seat which uses a conventional CMP seat mounted on a unique raising/lowering mechanism as a model for my Observers/Gunners seat.
