I have been corresponding with Jim Blacklock (A7CA Registrar) and Phil Baildon about the unusual Chassis Number which is in the old buff logbook that I'm using for my Cup Special. The number is CHA1-8191 and the logbook originally belonged to a Mulliner bodied car. Looking through the A7CA Registers and talking to various people has revealed 10 of these numbers:

Chassis	Car No.	Car	Date
19834	CHA1-830	Special	8/7/26
29386	CHA1-2491	GE Cup	1/3/27
44403	CHA1-4189	AD Van	15/10/27
45568	CHA1-4832	R Saloon	21/10/27
48088	CHA1-5936	AD Tourer (Aus)	1927
49918	CHA1-6664	Mulliner saloon	16/12/27
	CHA1-6692		2/6/28
	CHA1-8191	(Mulliner)	8/3/28
53723	CHA1-8531	GE Cup	23/8/28
55342	CHA1-9273	Mulliner	23/3/28

The 'Car No.' isn't a true Car No. as issued by the Works, but it's a convenient place to put the CHA1 number.

Can anyone add to this list?

P.S. Thanks to Ilke for formatting the table, but we can't work out why there's such a large gap above it...
