A90 Atlantic Distributor Advance Curve?

Hi -

I just purchased a 123Ingition Distributor to replace my not-so-trusty Lucas DVX4A unit.... which is frankly past its prime. This is for my '52 A90 Atlantic Sports Saloon.

The only thing I need to know is what is the advance curve on the old distributor so that I can program my new distributor to match the curve? Also, any idea on the specification for the original vacuum advance? Any help on information would be helpful. At the very least if you can tell me what maximum advance is supposed to be, that is the most important for me to know.

Any help in this respect will be much appreciated.

TIA!!
