Tricky - it's bookbinding leather , very thin .
Just remove the original and cut around the templates [ thin leather stretches more than the original hardened vinyl though ] Mine had been fixed by Oleg , so the vinyl had mostly been restuck . I don't know about other cameras .
i used a scalpel and dotted around the holes with the blade - not perfect but 1st effort .
Awkward around the s/t -
But it's just Evostick latext wood working glue , which sticks mostly to the leather -
So it's reversible !
I may do the s/t bit again , having bought a circle cutter !
I have a lovely regal purple/ blue for my avatar K4m - great with the black and 1/2 case !
I have also bought a K 4a 1970 - another suitable case for treatment !
I need a tan case for this one now - mine are dark brown .
To be honest , provided that the koverings are in keeping with the classic ethos of a vintage camera , I will gladly remove good vinyl from a K 4 .
This might be interference , but I love the transformation .
Sacrilege , perhaps , but some practise later - I would just love a cla Kiev 2 in tan leather !
