Thanks to all for their feedback..

I think that the one stamp (The 24¢ De Havilland Bi-Plane is a good one to have, 2009 catalog value of $30.00) alone has made it worth while the effort. Even though my main interest is IFS Cochin and British India, whenever the chance comes I try to gather old stamps from everywhere. In the auction I had mentioned, I managed to get about 6000 stamps in 6 world stamp lots. Now I am in the process of sorting those to get to the oldies...

. There are some lots from USA, Nederland, Austria, Australia, Britain and some commonwealth countries etc..
tomiseksj... I visited the link you had given. I think most of the stamps shown there are in the lot which I got of US stamps...
Meanwhile being a novice in US stamps, would like to know about the "bureau Pre-cancels" ones.
Once again thanks and regards
Thomas
