[78-L] Dating Another Homokord 78.

[Spats]

Hi!

Not for the first time, my computer seems to have chewed up some old 
e-mails, so I have to ask you once more about the 'code' for dating 
Homokord records.

I have here Homokord 2157.

LA TRAVIATA - Verdi. Ah! For'E Lui. Margherita Simonetti.
( 22718A and C23R pressed in the wax).
LA TRAVIATA - Verdi. Parigi, O Cara. Salvatore Giordano & Margherita Simonetti.
(24713A and C23R pressed in the wax).

I'm tempted to assume that these were recorded on 22nd July 1918 and 
24th July 1913 respectively.
Is this correct?
Please remind me of the significance of these codes.

Thanks.

Earl Okin.
