Broken glass window in wall
Which window did you need? I have a lot of DU-800 spare parts.
Any DU-600 series spare parts? I need either a filter for the filter wheel or a whole wheel. Even a junk one would do..... I think I can still measure the transmission of the filter I need (the one I have has gone frosty) even from a junk wheel or filter in poor condition.
