Graham chronograph flyback

Hello.Purchased some watch repair tools. Included is an HR made USA mechanical dust blower. I thought it may have a bellows or a diaphragm in it. It wasn't producing much air through the needle.It is the kind made of metal and inside it has a rubber disc. Looks like a dried apricot. It is made to fit tight enough to create enough resistance and back pressure to force most of the air through the slender metal nozzle which has a small hole to put speedy air through it. The rubber disc is not stiff........

.....Just "won" this little beauty eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low pricesnot sure it that's ok to post .....the seller does not look like a watch person.........looks like the occasional odds and ends person .....anyway ....according to the serial number it's from 1904 ....doesn't run ...but it's another 2 metal color case.....I think it's a very unusualcase......and the dial look kinda ok the way it is......not in the best of shap........
