Research on MPCs

Hank NEILL recently learned of the following individual who is  researching Military Payment Certificates and is interested in  speaking with any retired Finance Officer or NCO who may have   knowledge of the history of various series of MPC, photos of MPC or,  perhaps, even some samples he could acquire for his collection.
He is:  Mr. Jim AITKEN, #134, 160th Avenue, SE, Bellview, WA 98008. Phone:  (425) 641-6176. Email: james.ann.aitken@comcast .net.
