I think JimsCal is right, most of the quarter ton rule boats would have different charateristics.

I use to race on an MB24 built in Perth & I know they were originally built to the quarter ton rule. The Observer's Book of Sailing Craft of Australia and New Zealand confirms this, which states:

The MB24 is Dutch designers Van de Stadt's thinking of the Quarter ton rule.

Stats on this boat are
LOA 23ft 6"
Beam 9ft 2"
draft 4ft 5"
Displacem 1,950kg
sail area 356sq ft

Flicking thru the book other quarter ton boats mentioned include:

Admiral 26 - designed to rate 18 ft for quarter ton competition
LOA 23ft 4"
beam 8ft 4 "
draft 4ft 7"
displacement 2,041kg

Cavalier 26, described as " outdated by the latest dinghy type quarters.
LOA 25ft 6"
beam 8ft 9"
draft 4ft 8"
displacem 2,134kg

Spacesailer 22 "...recently been rated for Quarter ton racing
LOA 22ft 4"
beam 7ft 10"
draft 4ft
displacement 1,202kg

Also I believe that AVS is a fairly recent calculation, from around the 1990's. I doubt if you will find any AVS info on 1980's IOR designs.

Hope this helps.
