Hi guys,
i have had these for some time now in my collection but wanted to know if you could ID them and if they are real?
TUBE 1.


only other visible markings are EISH or could be FISH and 161..looks like lower case b underneath

TUBE 2.


i think this could be a version of a telefunken? has 51 in the diamond underneath.only other visible markings are eg.
i lost track of what i have and started to go back to the collection to roll in my revG.
any help is greatly appreciated.
 
Tube1: If etched code is i61 and Bxx(x) it is Mullard ECC83/12AX7 from Blackburn UK factory
Tube2: Looks original Telefunken Smooth plate
