The reason we decided to use the off the shelf jacket (M-65) is for ease of access for members, and for uniformity. Once we lean towards custom made, there becomes the issue with making sure everyone who makes the jackets uses the same color/material. You can see how the shoretrooper soft parts differ between makers now. Same with officers, there are quite a few shades of OD officers out there. Custom made is definitely an option but should go up to level 2 or 3. Like the metal vs leather grommets on the parka, since its a crapshoot on which grommets you might get from whichever source. But, keeping in mind a fan standing 10 feet away is not going to know the difference between the leather or painted metal, nor will they know the difference between an off the shelf (modified) jacket, or custom sewn.
Darren, I understand you have the source for THE buckles used on the respirator, but if they are that rare that only one source has them available, then they should be level 2 or 3 as well, with a reasonable alternative for level 1. You are keeping your source under wraps, so those of us without elite access are trying to do the best with what we can find without having to pay for elite access and international shipping.
All that said, please if you have info, share it so we can ALL enjoy this fantastic armor set. I cut and pasted what I could from other CRLs, tried to word what needed to be written up the best way possible. I know the telemetry unit wording needs to be updated now that there are better references available, that sort, I've just not had the chance to sit with it and write out the details. Would love to just say "refer to reference pic" in the CRL.
