I would really prefer vintage but wouldn't mind repros if they were at least quality, seems so many are junk.
True enough. It takes patience, and a touch of dedication.
Decent KW era belt can be found for circa $20, $30-40 for really clean.
Belt magazine pouch will be $5-10 (about $40 if you want the 30 round version).
Dressing pouch is $5-10 (a bit more with a correct metal dressing tin inside).
Canteens have become collectable of late, so a correct KW version is going to run $25-35; another $10 with the cup.
Now the Army M-45 suspenders are in good supply, but perversely spendy, probably $30-40 for a decent set that fits.
USMC suspenders are less common, but also less expensive--$10-20.
Best way is like the Johnny Cash song--one part at a time. Slower, but more sure.
Well, ok, so, I can't find any of my Carbine belt photos. I should have three--a 1945 version, a 1951 version, and a 1966 version. Danged if I can find the photos. Sigh.
