S.O.E. One-Time Pad on Silk - Opinions Wanted

[WWIIBuff]

Hello Gentlemen,

I know this is not a badge or insignia, but I assume someone here might know about these. If it is not OK to post this, then moderators feel free to remove it.

I have been offered this one-time S.O.E. code pad and documents to go with my S.O.E. B2 radio. I know there are various reproductions of these out there, but have never seen an original for reference.

Do any of you know if this might be an original or not? I would appreciate any feedback.

Thanks

John
