It's complicated

I've been all through the EE book and I can't figure out how to cite the following book.  

It was originally printed in 1948 in Wilton, Conn and the name of the publisher was not included.  The copy of the book I have is from the Library of Congress in microform format.  Using the Quick Check Models, I can't decide whether to use Book: Reprint or Image Copies Microfilm Publication.  I've uploaded a description of the book from the Library of Congress Catalog.
