They look like 6360s, 10 watt push/pull VHF PA tubes.? I can¡¯t be certain, though.

These tubes were literally dug up last weekend at a former "VHF Telegraphy" commercial site in the UK.

Does anyone recognise what they are ?

Ideally I'd like to know what equipment they were used in, date is likely 1960 - 1980, all the printing is lost to the rain/soil.
