ELC vs RM
RM is certainly darker. Seams are prevalent. Wool is significantly lighter as well.
I acknowledge that originals were on the this side. I have an ATF repro in a bag still and it is twice as heave as the RM. RM don't cut corners so assume they are spot on and ELC is somewhere in the middle.
Will probably grab a Navy (Blue) Bronson direct off eBay. Used up some Buyee points that were sitting there to get the RM cap. Fan of the ELC A-4 in design and spirit..... It has nips and has been overseas with me on a couple of deployments.
