I'm Looking For Info On Historical Foreign Destination Rates

I have a lot of early 20th century covers at the five cent rate. I also have a bunch to certain European destinations at one and two cents. I have heard this referred to as "treaty rate", but I have not been able to find much about them. I am interested in the time period and the countries involved. Many of them seem to involve banks. I also have a bunch of three cent foreign destination covers that seem to cover the same period of time when we raised our domestic rates a penny during WW1. My last question is how long did the five cent foreign destination rate run?

While SCF is the easy way to get this answer, you can also DIY further issues at:

(If they are not at home, try again in a day/two.)

At least in terms of Europe, there was a 2 cent treaty rate for the UK and a 2-cent direct steamer rate to Germany before World War I. For other destinations, it is more likely that you are looking at printed matter rates.

Would that make the one centers third class and the three centers war rate?

That link to the postal bulletins is a good resource for many things. I now have it bookmarked. Thank You. It did not really help me with my quest for international rates. Is anyone aware of a table or something online that gets into specifics such as time periods and countries involved in these reduced treaty rates? I am told there is a book called B&W International rates. I would prefer to find something online.
