The Photogrammetric Society Analogue Instrument Project: A Sixth Extract

The paper entitled The Photogrammetric Society Analogue Instrument Project was published in The Photogrammetric Record, 14(82): 565-582 and contained, as Appendix A, an extract from the Archive concerned with the history of the Zeiss Stereoplanigraph in Great Britain. Further extracts have appeared in each of the subsequent issues.
This extract, the sixth of the series, completes the history of the use of the various types of Wild instrument in the United Kingdom. It is concerned with the later post-war instruments, in numerical order, from the A7 Autograph to the A10 and therefore includes a note on one of the most popular and successful analogue plotting instruments ever produced, the Wild A8 Stereoplotter.
At the moment, none of the instruments dealt with in this extract appear to be under immediate threat. However, their role as production instruments is fading fast in most organizations but they are being retained, often for training purposes.
The Archive contains no mention of the last and most refined range of analogue instruments produced by Wild as their Aviomap (AM) series. With the benefit of hindsight it is now obvious that, at the time of their introduction, the transition from analogue to analytical techniques was about to take place at an accelerating pace. There is therefore no entry in the Archive for any AM or AM-U instrument; none (or perhaps only a very few) seem to have been imported into the United Kingdom.
