I envisaged having to carry out very little work on this set after being informed that the chassis had already been overhauled. I assumed it would largely be a simple switch of the chassis to my unblemished case.
As it transpired I couldn't have been more wrong - this was a good example of "caveat emptor" (let the buyer beware) and a lesson not to blindly accept the word or indeed the standard of workmanship of others as satisfactory.
However it did give me the opportunity to rebuild an A22 from scratch - something which I enjoyed enormously and still continue to get a sense of great satisfaction from every time I use or even look at this particular set in my collection.
