At the time, it was my only aviation tunic, and if my friend Dennis didn't offer me a very fine identified tunic grouping with solid provenance, I may have had it longer. However, the prospect of a research-able items really got into my blood. It is fascinating how a piece of cloth can take on a personality of its own in a way that makes you feel like you actually know the person who wore it.
Sounds like your wife has discovered the same feeling about identified items and how the research never seems to end. Just when you think you know all that you can, some obscure or unexpected paper clipping, letter or reference comes your way - and it starts all over again.
