Interesting stuff...
When I started this thread, it was to try to illuminate possible post WW1 use of the flaps.
We've moved on to adding some excellent reference material for a little known Enfield subject.
Identifying original examples, with clear images of repos is extremely useful for collectors and historians/ researchers.
Many thanks for all the input guys.
A side point re the flaps, I can certainly see an excellent use for them in the dusty conditions of the North African campaign.
