One of those apparently came partly lose and 'hooked' or snagged behind some metal parts of the received close to the drum. These strips are not al all easy to remove without taking out the complete drum (something I didn't dare to do, yet). Carefully bending the strip in shape again and very carefully tapping the strip into place (using a very light hammer (!!) with soft rubber head) I was able to get it back in place again (see pictures). The strip is not perfectly straight again but you can't see this repair from outside and the band switching is now smooth and without any issue.

Thank you all so far for your attention, tips, hints and advice! Also to the blog reader who offered me the PSU, thank you very much again!
