Hello Big Mike. I cannot react on the Bermuda stamp, not my area. The Kiautschou stamp is not of high value. I do have to point out, that the stamps you have shown are not in the best of condition, teeth missing and they also look a bit faded.
Do not stop posting or asking questions, there are enough people on the forum that will help you out.
If possible, the stamps you have shown us should be with al their teeth and not faded, a nice cancel that one can read is also helpfull.
