[ASR142]

The inner brim is made using 2 peaces of shaped cloth which are stitched to the inner crown part of the beret this is all ways done in the same way. The stitching is hidden in-between the lining and the woven part of the beret ( reattached liners are some times left with a join the wrong way round which is not shown in pictures on ebay ).
The inner brim is attached to a stiffening peace of hessian material near the edge by a lose tacking ( The black thread around the inside of the beret ) The leather trim is then attached to the this part of the beret creating the 1st row of stitching on the inside of the beret .The leather band is then folded over the edge of the beret outer and then stitched in place creating the 2nd row of stitching ( the one in the middle of the lose tacking and top row of stitching ) which goes through all of the layers of the beret at this point I can only presume that the ribbon is attached by a curved large blunt needle which would be slotted through the beret leather trim in a turning motion in 1 easy step and cut then tied of tied of .
NOTES
1 KANGOL produced liners in 2 colors during the years 1945-46 there is nothing wrong with these at all and tend not to get faked a good choice for a 1st purchaser of a airborne unit beret. They also tend to be a bit cheaper the example below is a 1945 dated example issued to the SAS during the late 40's early 50's .
2 some times the milliners ( hat maker's ) works label is found inside as can be seen in image 2 these are all ways in the same location towards the rear of the beret
