Why it matters
The SF and SG Silver Eagles were the entry-level six-cylinder Alvis cars of the early-to-mid 1930s. They were essentially up-engined versions of the Firefly and Firebird and bridged the gap between those cars and the Speed models and Crested Eagle. The Alvis Owner Club describes them as a sales success, relatively compact cars with a sporting character that were also smooth and quiet.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionSilver Eagle cars produced 1927-1936 according to the Alvis Model Register no. 21 (July 1995) | 2,6901 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
The Alvis Archive describes the Silver Eagle as spanning 1927-1936 and quotes the Alvis Model Register for some 2690 examples, of which 786 belong to the post-vintage period. A further source records that 200 SF 16.95 chassis were built before the SG 16.95 replaced it in late 1934, and that 500 SG Silver Eagles were made, the last despatched in October 1936.

Identification guide
How to tell an original from a replica or later conversion.
The SF 16.95 was introduced in late 1933 and the SG 16.95 replaced it for the 1935 model year. Both have a six-cylinder engine with a separate cast-iron block and head on an aluminium crankcase. The SF engine measured 67.5 x 100 mm for 2,148 cc, and the SG lengthened the stroke to 110 mm for 2,362 cc. Cross & Ellis supplied most of the saloon, drophead coupe and tourer bodies.
