farlymac, nice looking camera! As far as I am concerned, any Solinar-lensed Agfa is worth sprucing up with whatever mods or aids it takes to make it more comfortable to use.
It occurs to me that if you wanted to be really slick about it you could cut out and adhere a new focus scale directly onto the focusing ring itself, rather than the look-up chart on the back. Aside from being able to set the focus directly in your preferred units without having to do a conversion, another advantage is that you could make the scale marks at whatever convenient intervals you liked (e.g., 3.5', 4', 5', 6'', 8' 10', 15', 30', inf), instead of the odd numbers. The main downside is that it would take some a bit of effort to work out exactly where to place your scale marks since the focus scale isn't linear. But it certainly can be done.
Hmmm... and then you could even market them on eBay for say, $5 each. 🙂
