Serial Number registry?

[Hofmannhp]

curious.. the foilcals don't show any signs of manipulation to my eye..

they are definitely alnico magnets.

here are more numbers from the rest of the system:

PR8 serial 11949 (has silver dust cap)
C54 Cabinets 69152 and 69154

Hi ,

what I wrote about the LE8T isn't possible as Grumpy stated.
I have only two of 164 with SN and the (unconfirmed) date of 1985 with the numbers 37447 and 37457.....but this can also be a result of the owners (wrong) declaration of the age.
C54 in the registry go from 67110 to 70277 without any date and PR8 from 10011 to 58019 also without date.
