Today I received a parcel with a new piece for the colletion.
I bought it at an auction in Holland last week. And now I am very happy to have a cal 47 in my collection. Cal 47, Elgin III.
It was sold to a Dutch dealer in 1888.
There are some great posts in the archives about the cal 47/48
Here they are post 1 and post 2
And here are the pics of mine, case number is 1082 in 14K gold, most probably not by IWC.
