Plastic mirror collar / door lock seals

[Dungman]

At long last the chim is back in one piece. Almost.

Both the black plastic collars that cover the toadstool at the base of the door mirrors are chewed. Any idea if replacements are available, or anyone came up with a good alternative?

Also need new rubber seals for around the door opening lock / silver buttons on the rear wings. Any ideas?

Any suggestions much appreciated.
