I have two of these. The only marking on them is on the buckle and it is CS-3000. They are not long enough to be worn as an equipment belt or work belt and there is no method of attaching the free end to a seat. The only thing I can come up with is a seat belt extension. These two belts were in a duffle bag from WW2 along with the maintenance type coveralls the aircrews wore. Any ideas? Thanks.

That type of buckle was common on J-3 Cubs and other 1930s and 40s light types up until the 1980s when they were outlawed by the FAA. It could be that the free end looped around a bar on the seat or aircraft structure and trapped under a separate steel loop that you don't have.

Definitely not something used in a higher powered aircraft where serious quick release latches were used.

I don't know if the L-4 and other light L types used a military style metal to metal latch system or the civilian pinch type latch pictured.

So early civilian aircraft. Thanks for the response.
