Hi, sadly I never noted where I got mine from so I couldn't say what time frame they fit into. Sometime after 1943. Hopefully some-one else will have been more dilligent in their collecting and knows the timeframe of the various rats as they are still in use some 60 odd years after their first use.
When I served with the 7th Armd Bde in Germany 1969-74 we only wore the Jerboa on Combat Kit and from memory these were printed not woven.
