Accessories for aged Super Ikontas etc.

[literiter]

I have some Super Ikonta Bs. They all seem to have the same problem with attaching filters and hoods. (I know it's a little late to compain since they've not been manufactured for over 50 years in most cases.)

The Super Ikonta C, has a slightly more efficient system for attaching a lens hood, by machining a slot to receive a 37mm hood. The same hood will attach to the SI B, but a gentle breeze will dislodge it.

When I use hoods I'm rewarded with increased contrast and less flare, but I'm not accustomed to spend my shooting time chasing lens hoods when they fall off.

I've not tried filters yet on the Bs, but I think I'll have similar challenges.

Any ideas?

i cant say i have had any real problems, or at least if/when they were a bit loose i just bent the tabs in a little to tighten the fit and they seem to fit snug (as in the pics below). the Ikonta C is a better system, at least the post war i have is (not sure if the pre-war is the same). the hood and filters will either push fit or screw on
