I have a few questions on a few different Pakistani stamps:
1 - Below is Scott # 82 (1956) and Scott # 265 (1969). Both are of minimal value without the overprints, but I am wondering if they are worth anything with the Bangladesh overprints on them?

2 - These overprints look like Type A40 (1961-1970), and they show some overprints for this series in Scott, but not overprints like what you see on these stamps. Can anyone help identify these overprinted ones by Scott # please?

3 - This one is also Type A40 and I think it is Scott #140, but is that an overprint on it or cancel? I don't think it is a cancel because the gum on the back looks mint.

Cheers... Marc
