I am currently working on a good quality fusee ship's clock of unknowm make. It has a bit of history behind it in that it was present at the D-Day landings. Sadly over the years it has been treated badly having a cracked balance staff end stone and apparently being dunked in a bucket of oil! There was a pool of oil inside the brass case when Iremoved the movement. The clock is fitted with an English lever escapement which despite a thorough strip and clean I cannot persude to self-start nor obtain an amplitiude of more than190 to 200 degrees. A fob watch with an English lever movement which I possessed some years ago would not self-start either so is this usual with such an escapement and also is the ampltude sufficient? I should add that the movement without the escapement spins freely on less than a quarter turn of the key. If this thread is more appropriate to the watch repair section, please feel free to move it.
