SMA trainer, life raft and link trainer

[planewriting]

Can anyone tell me some facts (including years of service) and figures for SMA3 trainers, which served in the RNZAF? At Classic Flyers we have SMA3 number 1 and I want to write a suitable placard.
Similarly we have a World War II life-raft and also a link trainer. If anyone out there would like to put "pen to paper" on these three items, please feel free to do so by adding to this thread. 
Thanks

Peter, do you know the serial of the link trainer? Thinking about adding a page to NZDF Serials for these.
Also, for my memory, a photo of the SMA 3. If it is what I think it is, I worked on these waaaaaay back.
