Made most likely with Adam's & Westlakes parts.
I have never seen this model before.
Similiar in design to a lake and river model but uses a 6 - 1/4 tubular globe
Button release tilt open design 
Sangster fount with a  No.1 whale oil burner
Unmarked , no patent dates 
Condition - very good
Barn fresh unrestored condition 
Very nice example of a rare model , clean smooth tin.
No pitting or heavy rust.
No visible condition issues present.
