help with walther adjustable rear iris

[R.E. Smalley]

I have an adjustable rear iris that has 5 color filters plus polarization filters. I need to take it apart to clean it. I tried once and got it locked up, but it seems to work now.

The destructions are in German. Anyone have a translation?

Thanks all,
Ralph

The iris is likely to have been made by Gehmann or Centra for Walther, so it may be worthwhile looking for disassembly/maintenance instructions for these products rather than for a specifically Walther-made iris.

A photo might be helpful. I've dismantled my Gehmann several times for cleaning.
