Just finished servicing a 390 and I was pleasantly surprised to see that the removal of the running seconds post was done correctly.
Although the pivot was not rounded and was left square, at least it was correctly cut off with enough of the post remaining to allow correct height and finishing.
On the same movement the top escape wheel jewel was cracked in half...very unusual to have cracked jewels, so I am guessing this was done by whoever modified the post...can't win for loosing sometimes...
