I purchased these items today, from a dealer, and I’m really liking them. Seller stated the tunic was a summer tunic dated 1942. From reading Nick’s uniform thread, it’s an unissued item due to stamp "B" being blank? I’m assuming the collar insignia was added as a display due to the tunic being unissued. Tunic is made of cotton.

The breechers also came with it and the seller stated it was dated 1944.

I’m still learning so I hope it’s all good? I’m waiting on Mike Hewitt’s book to get here. Screenshots of the items are all I got right now.
