Wanted: two particular vintage magazines with aviation articles

[PeachesPQA]

Hello, my name is Ann King and I am writing a bio (and a series of historically based adventure novels) about my aunt, an early aviatrix, late l920's era.

I need two magazines: (1) Popular Mechanics June l930 and (2) Aviation Mechanics July-August l930.

I am in the research, grant writing and development field, so am not looking for advice re museums, libraries, university archives--I want the actual magazines listed above for family history archives. I periodically also check vintage magazine sites as well as Ebay and have been successful in acquiring other vintage copies that pertain to my writing subject matter. Am also aware of vintage Popular Mechanics online with Googlebooks.

The assistance I need is: if you or know someone who has either or both of the above magazines, please contact me as soon as possible. Thanks very much.
