*Rare*Lee Enfield #4 central competition sight

This rare hard to find #4 central competition iron sight made in Australia.   

Some minor rust areas and slight damage to the eye cup.  

Hole slide #7-#4  

All adjustments are smooth and have positive clicks.  I've kept it oiled and did my best to further preserve this antique. 

No, there is no mounting screw.  It's a 10/32 if I remember correctly.  

Will send more pictures via text if someone is interested.   

Price $120 includes shipping across Canada.
