Hi Jimbo,
we had small e-mail talk some time ago.
I noticed on this forum results from Viareggio tournament in Italy, for 1920s. What was your source ? I tried to search some Italian results for 1920s, but it is really difficult to find something in the old newspapers. I only found something on tennisarchives.com or thetennisbase.com, but it was only some of San Remo, Merano (some years) and Bordighera tournaments (mens results). On wikipedia I found Italian national champs winners (all-time), and found web with Napoli tournament winners (all-time) and Parioli tournament winners (all-time). Nothing more. I suppose there was much more tournaments in Italy in those years, but it´s really difficult to find it. Magazine Tennis Italiano started in 1927 (as far as I know), so from this year on - it should be easier.
Regards and thanks for the answer
Peter
