I went to staff an Elgin 573 today..I had ordered several #6167 single roller staffs because this is what the book said was the staff number for the watch...I took the balance out and to my surprise it was a double roller...I can not find anywhere that the 573's called for a double roller escapement...Any thoughts...I did have a couple of DR staffs for the 571's #6166 and it looks like they will fit..I was just wondering if anyone else had ran into this on these watches...Serial number of the watch is U630261...Gary

Mistery solved..Thanks...
