Yo,
I've got two PT-015's, both with dented front thread areas (one dent each). I can not screw on my new type 2 Inon WAL. The housings are fine except for the dent. I have tried to bend it out to no avail.
Olympus says they do not sell that part to consumers, but I could ship it to them for repair! The ring screws on and off by hand, it's hardly a repair situation.
Any help or suggestions would be appreciated.
