Yea, while working on my workshop in Poznan i also found all kinds of antique stuff from the times of USSR. Some grease, a soup can, a few bottles of vodka hidden in the ventilation, some wooden coils. But the coolest of them all is lots of old switches, free cables and a few powerful electric motors.I found this in my coal shed / bicycle workshop, a lovely tin of grease from Jedlicze, a town in southeast Poland, which I am now using when I rebuild my hubs. Before that I had to spend some time carefully removing the crud from around the lid so that none of it fell inside when I first levered the lid off. Behind it, up against the wall to the right, is a large hammer that I also found in there, lodged behind the furnace.
Finally, rather than being some kind of space motif or or oil leak, the red and black on my bench shows that I have not been a total bum in the build.
