zing went the strings woops

[Joe And Penny Goss]

Hi all,
Today I was given my winters work, a 1921 H C Bay grand.
A local tech delivered it in pieces, totally dismantled.
All the parts seem to be there, but the kicker is that there are new bass
strings from Schaff,
but no record was made of the plain wire.
Could one extrapolate the plain wire sizes from the bass
strings by measuring them and running the string lengths of the unwound
strings?
How should I procede?
