These confuse me somewhat,
listed in edefil, but I have never seen
"serie 1" or "serie 2" before in cat, only 3 or 5
I have no idea of that significance
but the others are min CV in 1988 20c to 80c
I'll leave the guesswork up to you, unles someone
specialises here.

Ah!
serie 1 shown in 1960 Gibbons
