Thanks for the kind words everyone. I'm glad this is of interest to the community.
Great photos, Tonomachi. This reminds me of a post by Jon (Postwarden) some time ago:
“It is worth noting that not until January 1945 did the Ordnance Depot issuing the parachute badge suggest that cloth could be save by supplying the Badge, Arm, Parachutist cut to shape instead of bring rectangular which clearly proves the issue badge was rectangular and must therefore have been trimmed to shape locally - which explains the numerous versions that exist.”

From that, we can assume that factory trimmed wings were issued after Jan 1945.
