Hi,

Could I get some help from here?
I am looking to buy a 7020/0 with a serial number #2795XXX.
The serial number actually is 7 digits long.
I think it is an early 70s.

I have tried to read for some information here, but it seems quite hard to find.
What can you tell about this serial number? I thought its always 6 digits? Or 5?

Many thanks in adwance!
