Gran Premio Vigorelli

Misano, 23 Apr 1973

All cars are 1.6-litre F3 unless noted.

Notes on the cars:

1. GRD 372 (Sigi Hofmann): Sigi Hofmann (Stuttgart, Baden-Württemberg, Germany) raced a GRD 372 in European F3 in 1973, entered by Jörg Obermoser-Eurorace GRD. Like Gernot Lamby's car, it was often referred to as a GRD 373, but was referred to at least once as a 372, indicating it was a 1972 car upgraded to 1973 specification. He appeared at least six times in German F3, and also at Misano and Zandvoort. Nothing more known.
2. Lotus 69 (Roberto Filannino): Roberto Filannino raced a Lotus 69 in Italian F3 in March and April 1973, using Ford engines and entered by Scuderia Torino Corse. Nothing more known.
3. Lotus 69 [71/69-2.F3] (Marcello Rosei): New to Claude Bourgoignie and raced in European F3 in 1971, using Holbay and Novamotor engines and entered by Johnson's Wax Team Belgium. Sold to Marcello Rosei and used in Italian F3 in 1972 using Wainer Alfa Romeo engines and entered by Scuderia Meneghina. Retained by Rosei for 1973, again with Wainer Alfa Romeo engines. Retained again by Rosei for the start of the 1974 season, when it was fitted with a Repetto Lancia engine and entered by Scuderia Varazze Corse. Rosei then acquired a March 733, and the Lotus-Lancia was sold to Sergio Rosso, who raced it in Italian F3 for the rest of 1974. Retained by Rosso for 1975, but he was entered in a Lola at some races that season. History then unknown until acquired by Philippe Demeyer (Belgium) in 2018.
4. GRD 372 [023-F3] (Fernando Spreafico): New to Fernando Spreafico and entered for him by Scuderia Italia in Italian F3 races in 1972, usually using Wainer Alfa Romeo engines. Retained by Spreafico for 1973, again in Italian F3 and entered by Scuderia Italia, but now with Novamotor Ford engines. Retained again for 1974, when it was described as a 373, used 2-litre Alfa Romeo engines and was entered by Scuderia Concordia. Retained again for 1975 and for 1976, after which it was replaced with a Chevron B34. The subsequent history of the GRD is unknown.
5. March 733 (Piergiovanni Tenani): Piergiovanni Tenani drove a Trivellato Racing Team March 733 with Novamotor engine in almost all races of the 1973 Italian Formula 3 series up to August, after which he missed the last few races. He retained his car for 1974, when it was updated to a 2000cc Novamotor twin cam. Subsequent history unknown.
6. GRD 372 [026-F3] (Aldo Fasan): New to Marcello Gallo for Italian F3 in 1972, but raced by various drivers that season, usually entered by Scuderia Delta Corse. It appeared again in 1973, again for various drivers. It was next seen in 1975 when it was described as a 373 and entered by Comete Racing Team for Giancarlo Comazzi to drive. Raced by Duilio Ghislotti in 1976. Subsequent history unknown.
7. March 733 [713M-1?] (Livio Franzoso): Livio Franzoso raced a March 733 in the Italian F3 series in 1973, entered by Scuderia Patavium and continued to race the car in Italian F3 until the end of 1975. Subsequent history unknown.
8. March 713M [7?] (Dietmar Flöer): New to Jim Gleave's MRE (Bourne End, Buckinghamshire) according to March records but MRE do not run a 713M in 1971. Believed to be the car raced by Dietmar Flöer (Stuttgart, Baden-Württemberg, West Germany) in European F3 in 1971. Retained for 1972 and for 1973, and reppeared again as late as 1975. Likely to be the "712M" that Flöer raced in a German national F2 race in August 1975, then the March 713M he raced in F3 at Wunstorf in 1976 and Diepholz in 1977, and may well be the F3 Eigenbau he raced at Hockenheim in May 1980. Subsequent history unknown.
9. Brabham BT28 (Giauco Maselli): Alessandro Pesenti-Rossi raced a Brabham BT28 in Italian F3 in 1971. It went to Scuderia de Passatore for 1972, fitted with a Wainer Alfa Romeo engine and driven by Massimo Ciccozzi in the early part of the season. Ciccozzi progressed to a Branca, and the BT28 was taken over by Angelo Ancherani later in 1972. Then to Giauco Maselli for 1973. Reportedly retained for 1974 and 1975, and presumably the BT28 raced by "Claudio" Maselli in 1975. Subsequent history unknown, but this car was advertised by Paolo Ricciuti (Pescara) in March 2021, still with Clauco Maselli's name on the side of the bodywork. The frame number of the car suggests a chassis number somewhere in the range BT28-5 to BT28-20.
10. March 733 (Bruno Pescia): Bruno Pescia drove a March 733 in the 1973 Italian Formula 3 season, entered (at least from June onwards) by Trivellato Racing Team. Nothing more known.
