In response to Primreamer, other photos that I took at Strathallan during my visit there in 1976:
Shackleton:

And a photo of the Hudson, but taken in 1973:

And I'll shortly post a link to the one other photo I took during my "over the fence" visit in 1973, showing a Sycamore, a Tri-Pacer and three(!) Ansons in the distant background.
Also, but now from my 1976 visit, link to a photo I took of Miles Monarch G-AFLW.
