Thanks Tim, appreciated. The days tend to get long in isolation even though I have plenty of tasks to attend to. However, collecting the energy to recharge "batteries" every day gets challenging over time I can assure you. Plus I miss my kids who live about 40 km away.
On a side note, the Rodenstock which frequently is frowned upon because of its massive field curvature and heavy spherical aberrations becomes more and more sharp across its projected image circle the nearer you can get the lens to the sensor plane. Unfortunately there is a shutter that limits how near you can approach thus infinity focus seems impossible at present. The lens, an integral part of X-ray imaging machines in the old days, carried a very hefty price tag commensurate with its heft and bulk. Lots of thick, high-index glasses inside. I do have seen outcome from this very lens copy on a high-speed TV camera and the rendering was high contrast, and the image very sharp.
