The other day I accidentally dropped the original Bakelite lens cap of my '53 I-22. I watched it shatter into pieces as it hit the ground. Looking around the house I found that a Gat*rade bottle cap fits just right.
The inside thread of the bottle cap holds on to the front ring just right - and does not hit the focus scale ring, when collapsed.
Even fits into the ever ready case.
Still sad about losing the original cap, but happy enough, to have found some protection.
