The reason I asked about the size, date, maker,I had one many years ago that had a post war civil liner in. Which I sent back to the seller.
So you can't be to sure until you get it in hand to check the leather sweat band,but hopefully yours will be fine.
Here's the pictures, as you can see, it was laced up wrong, & no date on liner.
Whether the shell was post war too, not sure.
The size number on the shell should match up to a certain size of the liner.
& yes, they are hard to find, the HCRAC even more so.
