ADAC-Flugplatzrennen Bremgarten

Bremgarten, 23 May 1971

All cars are 1.6-litre F3 unless noted.

Notes on the cars:

1. March 703 (Dieter Kern): Dieter Kern (Ransbach-Baumbach, Rhineland-Palatinate, West Germany) ran a March 703 in the 1-litre class of German Formula 3 in 1971.
2. March 713M [1] (Hannelore Werner): New to Eifelland Wohnwagenbau for Hannelore Werner to race in German and European F3 in 1971. To Heinz Lange (Neuburgweiler, Baden-Württemberg) at the end of the season, and used in the Italian F3 series where Lange hired a Brabham BT35 from Scuderia Italia and the 713M was raced by Piergiovanni Tenani, Clois Avigni and "Shangri-Là" (Romano Martini). It may have been raced once by Livio Franzoso in 1973, but apparently retained by Lange that year. Sold to Werner Fischer (Waiblingen, Baden-Württemberg) for 1974, then to Biagio Brandi (Bad Homburg, Hesse) in 1978, and then to Marcel Biehl (Mönchengladbach, North Rhine-Westphalia), who posted pictures of the unrestored car on Facebook in November 2013. Immaculately restored and raced by Biehl in 2015. Sold to former owner Werner Fischer in 2016, and raced by him in the German HRA series in 2017 and 2018.
3. March 713S [8] (Willi Sommer): New to Eifelland for Formula 3 and delivered in March 1971. Although there is no contemporary identification of this car's first driver, it was identified by Bonhams in a sale in Germany in August 2003 as Willi Sommer's car, commenting that the car had its original ONS-Wagenpass issued in 1971. Sommer raced a March 713S through the 1971 season as part of the Eifelland Wohnwagenbau team. According to Chris Townsend, it then went to Hans Deffland (Munich, Bavaria) for 1972, entered by Formel Team München. After the 1972 season, Deffland exchanged it for the crashed Porsche 910 of Walter Proebst (Adlkofen, Landshut, Bavaria), and Proebst raced the car in German hillclimbs, initially in the F3 class and later in F2. Bonhams did not account for its history after 1971 until it was restored "1996-99 by Auer of Dortmund".
4. Brabham BT28 (Jean-Bernard Mermod): New to Jacques Rey (Switzerland) and entered for Jean Blanc (Bernex, Switzerland) in F3 in 1970 using Novamotor engines. The chassis number of the car is not known but it would have been a new 1970 car. Blanc retired mid-season, a decision he would later reverse, and the car was entered for Bob Wollek at Brands Hatch in August. According to Philippe Demeyer, the car went to Jean-Bernard Mermod (Salgesch, Switzerland) for 1971. He raced it in the 600cc-1300cc Rennwagen class in Swiss national racing so it is likely to have retained its original 1-litre engine. Given how few BT28s appeared in Switzerland, this may be the BT28 of Edgar Richoz (Vionnaz, Switzerland) in 1972 and Toni and Arnold Kaufmann (Interlaken, Switzerland) in 1973, all of whom used it in the new Swiss 1000cc Rennwagen class. Subsequent history unknown.
5. March 713S (Klaus Enders): Klaus Enders (Wetzlar, Hesse, West Germany) raced a March 713S in 1971 season as part of the Eifelland Wohnwagenbau team, but was seen mainly in national events. His first known 1971 race with the team was in May, so he may have taken the place of Franz Pesch. Enders was better known as a motorcycle sidecar racer, and he returned to motorcycle racing after 1971. His last known race in a 713S was at Mendig at the end of August 1971, and as all the other German 713Ss raced in the Eifelland-Caravaning-Pokal at the Nürburgring in October, this must have been the car driven by guest star Howard Carpendale, a German-based South African singer. Subsequent history unknown.
6. March 703 (Josef Kremer): Josef Kremer (Köln/Cologne, North Rhine-Westphalia, West Germany) ran a March 703 in the 1-litre class of German Formula 3 in 1971.
7. March 703 (Peter Krause): Peter Krause (Grefrath, North Rhine-Westphalia, West Germany) ran a March 703 in the 1-litre class of German Formula 3 in 1971.
8. March 713S [6] (Wolfgang Bülow): New to Eifelland for Formula 3 and delivered in March 1971. Identified by Autosport as the car raced extensively through 1971 by Wolfgang Bülow (Koblenz, Rhineland-Palatinate, West Germany). To Utz Schad (Oberafferbach, Johannesberg, Bavaria) for 1972. Subsequent history unknown.
9. Brabham BT21B (Roger Rey): Jean-Bernard Mermod (Salgesch, Switzerland) first appeared in F3 with a Brabham BT21B at Hockenheim on 10-11 August 1968. He raced the car regularly in the Formel 3 class in Swiss events until the end of 1970 when it passed to Roger Rey (Sierre) who had previous driven a Formula Super Vee of considerable age. Rey continued with the car in the 1000cc class, mainly composed of former 1-litre F3 cars and was still winning his class in the car as late as Lodrino in April 1974. He sold the car to Marcel Speiss in 1975. Paperwork with the car uses the chassis number BT21/37, the number of Ingvar Pettersson's BT21. As Pettersson retained this car for 1968, it overlaps with the history of Mermod's car. Something doesn't add up.
10. March 713S (Hermann Unold): Hermann Unold (Ludwigshafen, Rhineland-Palatinate, West Germany) raced a March 713S through the 1971 season as part of the Eifelland Wohnwagenbau team, using a Schntizer BMW engine for at least part of the season. Unold did not continue with Eifelland after 1971, and the fate of his March 713S is not known.
11. Brabham [BT21] (Carlo Breidenstein): Carlo Breidenstein (Freigericht, Germany) raced a Brabham in Germany national events between May and August 1970 and his car has been identified by the F1 Register as a BT28. However, a photograph on formel3guide.com shows a BT21 or BT21B. Nothing more known.
