Du-Lite Blued Carbines, Muzzle to Butt Plate

[Bruce McAskill]

So Parkerizing was a top secret process during WW2? Guess they forgot to tell companies like Eddystone who used it towards the end of WW1 on their rifles that it was top secret. Funny though is most parts on early carbines were all blued like barrel bands and of course all bolts. Guess bluing wasn't top secret at that time.
