The correspondence file with the car notes that the body had to be remade in Argentina as it wasn’t strong enough to cope with road conditions. Greene also notes problems with the front axle, and HF3193 was shipped back to Bentleys in July 1931 to be extensively overhauled, and the body refurbished by Vanden Plas (Bentley’s Service Department was based in premisses leased from Vanden Plas, adjacent to the latter’s main coachbuilding works). The invoice notes a new 15/50 (3.33:1) crownwheel and pinion, and the fitting of a reconditioned front axle beam. (The number is painted over so I was unable to check this. Replacement Bentley axles usually have the chassis number of the car they came from, so if the paint is scraped from the top centre of the beam to show the number I can correlate this with repair work in the Bentley Service records.) The block was rebored and fitted with special pistons, as Greene wanted the engine tuned for performance. The 1933 engine repair work notes hour-glass pistons, as used in the works Bentleys. The Service Department fitted cable-operated André Triplex telecontrol shock absorbers, with the original Hartford friction shock absorbers retained at the front alongside the telecontrol units. At this date HF3193 was still fitted with a cone clutch and cone clutch pattern pedals.

In May 1933 engine HF3196 suffered a major failure, so Greene removed the engine, crated it up and shipped it to Bentley Motors. The engine was stripped and completely rebuilt as per the invoices in the file; the work is also detailed in the Service Record, as above. The sump still bears evidence of substantial repair work. The last entry in the Service Record, dated 1935, is for back axle parts sent out to Greene; the file contains a telegram dated 25 January 1935 ordering a differential assembly complete with associated races, marked "urgent". (The entry in the Service Record is obscured by a pasted-in slip for the 1933 engine work.)
