I would probably contact a local Lead Paint Abatement company. Paint is very localized. I.E. people in dry climates needs a different kind of paint from people in wet climates. Different temperature ranges, amount of sun, etc etc. The types of paint across various countries is usually quite different. As such, they probably have this information on hand for your region, or can easily tell you how to access records and such; and some might even provide you with the records.
