Raimey,
My old eyes read that as 813. Since the two sets of numbers were stamped in different fonts, I opined it was relined. I think the originak proof was in the 8th month(I guess it could be 3rd) of 1913 in Zella-Mehilis, with ledger number 416.If I'm correct, it was relined and proofed in the 9th month 1975, with ledger number 22( 27).This can be verified, if a "repair" proof can be found on the side or ahead of the marks shown. I put a more extensive answer at the GGCA site. As always, I may be mistaken, and eagerly await someone correcting me.
Mike
