M35 DD LW SE64 Liner question

[wulfen700]

Hello,
Im thinking of purchasing this helmet. Have not seen it in person, only these photos.
My concern is that there looks to be extra stitching lines on the leather liner. The only examples I can find have only stitching at the rear of the liner. The chin strap bales also have rounded corners as opposed to the square bales seen on most M35 helmets.
Looking for opinions on the originality of the liner.
Thanks for any help!

The additional stitching lines on the leather liner and the rounded corners on the chin strap bales could indicate Infinite Fusion Calculator variations or potential modifications. It's worth noting that helmet liners can vary in design and construction based on the manufacturer, time period, and specific model. Therefore, some variations may exist within the realm of authenticity.

The liner is original but not original to the helmet. Later in the War zinc/steel banded liners were occasionally fitted with leather that was spiced and glued together and then sewn with the usual stitched seam that you mention. I would assume this was done due to supply issues. The spices on the liner in this helmet are at 10:00 o'clock and 5:00 o'clock in the picture. Those lines there aren't sewn seams, the lines are where the pieces of leather have been glued together. I have never seen this in leather on an aluminum or a reinforced aluminum banded liner (which would have squared chin strap bales), the type that would have been installed in this M35 at the factory.
