Rick, you have me at an advantage. Im a country boy used to playing with pumkins. What is a "microfiche"? and a "NARA"? I picked this letter up at a deceased estate auction along with a comprehensive personal war item collection of one Captain Charles Douglas Sonn, his tags show the ID number 141195. It looks like he was with the British Intelligence, Middle East. The signature does not look to be original, rather the "mass produced" type. The paper is quite thin and a wee bit brittle. Im a bit weary about handling it too much. Thanks for your input. I appreciate it. regards Thomas
