Pitkin & Brooks Carnegie / J.J Niland 
Danube American Brilliant Bowl. 
c.1908-10
8 1/4" diameter.
3 5/8" high.
This pattern has been known
to be cut by these two makers.
Both makers highly regarded. 
Cheers : )
Condition:
Really nice antique condition. 
One small ding on a tooth and 
one on side (last two pictures pointing with stick)
Everything else seems to look good.
