Scuderia Ferrari headquarters in Modena in the 1930s, this is 31 Viale Trento Trieste in Modena. Not sure what the trucks are.  Enzo Ferrari had moved in here in 1929 and named it "Garage Alfa Romeo - Scuderia Ferrari", selling Alfa Romeo and running the Scuderia Ferrari racing team.<a rel="nofollow" class="external autonumber" href="https://www.comune.modena.it/lecittasostenibili/atlante-delle-architetture-del-900-di-modena/le-architetture-industriali/schede/garage-ferrari">[1]</a>. <hr>The first truck (far left) was used to support motor cycles.<a rel="nofollow" class="external autonumber" href="https://www.alfabb.com/threads/1950s-scuderia-ferrari-alfa-truck.50281/page-2">[2]</a>. The last truck (far right) was seen in a different photograph, where they were getting ready for the 1933 Mille Migla. This is according to pages 583 and 610 of Simon Moore's book "8C 2300", published Parkside Publications, 2000.  Picture credited to and copyrighted by the "Spitzler &amp; Zagari" collection, which the book describes as a "collection of photos recently purchased from Franco Zagari by Matt Spitzley." However, since Zagaro was born in 1930, this is probably taken by Ferruccio Testi, whose many pictures were rescued by Zagari.
