I went through the archives with this title and read all the posts. Answered my questions about the large screw in the back, whether to oil the acting surfaces of the pawl and EW, and how to substitute the battery holder. As to this clock, there is an inscribed plate dated 1978. It is now running with a new battery, and keeping perfect time, but I doubt anyone has worked on the clock for many years, since it still had a paper enclosed Horolovar battery pack that looked like it had been made in 1978. I'm assuming it would be a good idea to oil all the pivots of the movement, but assuming has sometimes created negative outcomes for me. Advice please.
