What does the number after the serial number mean?

[iainp]

I'm having a fantastic time identifying all my black and brown cylinders having bought the Ultimate Phonograph Cylinder Handbook. Can someone tell me though, what the number after the serial number means?
This is actually a Columbia cylinder, Anvil Chorus, number 1582, released September 1900. What does the 6 refer to please?

Regards,

Iain

It's probably the take number. On the Edison BAs, they used a series of dots (take #) followed by a number (mold number.)

I agree with Bill. By the way you will find the little dots and numbers on Wax Amberols as well.
