were 3 tone hurries still canvas winged?

Yes, all locally produced Hurris had canvass wings.

Yugo Hurri is somewhat of an odd bird, there was a bit of difference between standard Mk.I (early) and the 6 original planes build according to the Yugo order, some minor changes were demanded that would later be accepted for all subsequent RAF Hurricanes (the metal winged ones), and there were some little differences in the canopy framing that remained unique to Yugoslav Hurries.

They were armed with 8 FN-Browning machineguns in 7,92mm caliber (Mauser bullet, like the one used by Germans).

First 6 machines that were delivered from Britain had canvass wings, two-blade props and Merlin II engines. These were used as pattern for local production, as well as served for pilot conversion training.

Second batch of 6 machines also had wooden props and Merlin II's but have been delivered with metal wings. Technically, they were a Mk.I (early) powerplant coupled with a Mk.IA airframe. These were the only 6 metal-wing Hurris in RYAF (numbers 7 - 12)

All locally produced machines however have received Merlin III's with 3-blade metal props (like standard Hurri Mk.IA), because the production of the older version of the engine stopped and newer ones have been delivered instead. But the planes still had canvass-wing airframes like Mk.I (early). Some 36+ of these were built and about 24 more in production at the time of German attack.

At this time the original 12 British-built planes have received 3-blade metal props, locally built.

Also, except for a handful of examples all Yugo Hurris had only the ring-and-bead sights, no reflectors.

Yugoslav-produced Hurris have also been slightly overweight compared to the British-produced examples, by about 40kg.
