WW2 British light weight gasmask with filter 1 (No.3)

This is a very hard item to get these days.
You can see the second type gasmask that was used by the British forces and more specifically used by the paratroopers and commando’s.
I have 2 versions available at the moment.
It is complete with its carrying case and does also have the filter.
How ever, the filter has a post war date.

Markings: see pictures
Condition: mint / light used
