Elgin Grade 345, Greasy...

Here's a grade 345 that had a layer of some sort of grease, together with WD-40.

It's not quite done yet, but it ticks.  There's still a lot of work to do yet, and it will definitely be apart again to get thing right.

Getting WD-40, the worst thing ever for a watch, off a hairspring is not an easy task.  It takes a lot of by-hand work.
