Perhaps with this 'N-85', Bob Noury was anticipating the Fleet 80 engine change? FWIW, my Noury list is:
Noury 'Monoplane' - Jan 1940, 2-seat high-wing monoplane*
- 'Monoplane': 1 x 65 hp Continental A65-3, c/n 1, CF-BPX
-- * Side-by-side seats, strut-braced wood wing, span 11.20 m
Noury N-75 - Late 1944, 2-seat* high-wing monoplane
- N-75 Series 1: 1 x 75 hp Continental A-75, c/n 1, CF-BYW
-- * Side-by-side, wings as per 'Monoplane', span 10.11 m
-- Fleet 80 Canuck: Sept 1945, mod.** N-75, CF-BYW-X***
-- ** 85 hp C-85 lower/further fwd, metal subst. for wood

On designations, presumably 'N' is for Noury, 'T' for Tandem?
BTW: Noury Aircraft Ltd was established in 1942 in a former fruit cannery (or winery, depending upon source) at 928 Queenston Rd., Stony Creek, Ontario. While designing the N-75 and T-65, Bob Noury was placing ads in
The Ottawa Journal in March 1944 looking for partners"
"Any company that would consider manufacturing light aircraft parts or handle an agency are Invited to write Noury Aircraft Limited Stoney Creek, Ontario."
After the N-75 sale to Fleet, Noury Aircraft Ltd carried on operations sometime into 1946 - in June or July, Noury Aircraft overhauled DH.60M Moth CF-CFR at Stoney Creek. In September 1946,
Aviation Week had a note in its 'Aviation News' section:
"Latest addition to Canada's aviation industry is Noury Aircraft, Ltd., recently organized at Stoney Creek, Ont., to produce a new tandem trainer."
But, by that time, Noury Aircraft Limited was probably already out of business.
