It's actually a Thermarest inflating sleeping mat, manufactured for or by the British Ministry of Defence and is standard G.I. issue. Mine is brand new, dark earth colored, comes with a bag and two soft elastic bands to keep the mat in shape. I took some pics of the tags:
The NSN is 8465-99-310-9203.
Here you can see who imported it. Made in China.
This is a picture of the mat when I first unroll it and loosen the valve.
This is a closeup of the valve. Unscrew counterclockwise all the way and wait up to 10-15 minutes when new, or 5 minutes after first few uses. The mat self inflates. Do not use hand pump to inflate or over-inflate. Tighten valve clockwise to seal and use. To deflate, unscrew valve and roll slowly.
A closeup of the mat texture. Very durable.

Measurement: 4 feet x 21 inches. The weight is a little over 19 oz. Very small, light and durable.
