This may be a complete hash, but taken from Wimpffen's racing appendix and also a few web posts, this is how I think the six Elva 300s look in terms of early history. I'm also hoping that 005's might be correct!

“ElvaRacingRoger” quotes on website that a further chassis was as follows:
“300/ (no car number shown)... colour red; 1100cc Cosworth powered, engine # 462603; 5-speed Hewland; "cooler in front - 6 row rad, side & brake vent, stiffened chassis"; for RIECHAL”. Obvious candidate is -005, however the engine number does not tie in with the number shown on the chassis plate of -005; and “Riechal” does not correspond to any known driver/owner.
A few other notes/queries:
1. Peter Ellis drove an Elva 300 at Oulton on 07Apr62, the same day Ashmore was there in 003: Ashmore drove as #97 in Race A and Ellis as #120 in Race B. Same car?
2. Chuck Fredericks drove an Elva 300 at Continental Divide on 02Jun62 but no obvious candidate for a car: 005 maybe?
3. James Mall shown with an Elva 300 from October 1962 to July 1963. No idea, but likely not 001, 003 or 004.
4. Clark Sturdgess shown with Elva 300 from April to October 1963: Chassis 003 again?
As I say, probably a bit of a hash job, but hopefully it will stimulate a bit of trivial conversation. I'm not even looking beyond the mid-60s to untangle the rest!
