Originally, it came with barrel sights (gold bead front and typical stepped leaf rear), and with a Marbles tang sight.
The barrel sights shouldn't be too hard to find, either from Browning/Winchester or on ebay, etc. The Marbles tang sights are also pretty easy to find and can probably still be ordered directly from Marbles if you don't mind paying full retail.
I wish I could find single shots with 12X Unertls on them!
