[GreenKeys] M14 TD for PYTHON crypto ?

[Nick England]

Does anyone have info/photo on the US Navy's CSP-2699, the PYTHON key tape
reader? I assume it was a M14 TD variant of some sort, but don't know
anything for sure.

For transmission, the PYTHON system read a one-time key tape which was
added (ex-or) to the plain text from a TD or keyboard. At the receive end,
this process was reversed.
