That rig was WAY too much
Original belt should be about 40 bucks, holster 100-140. Join a collecting forum. I recommend usmilitaria.com
example:
"Offering this nice set, came together. Belt is marked 'US'. Mag pouch is marked on rear 'ERO MFG CO 1942' and inside 'W-4925'...$45 shipped domestic or trade for USMC or WWII German"

"- Early WWII Canteen and Pistol Belt Set: Canteen cover is dated 1942, canteen and cup are dated 1918. The pistol belt is dated 1941 and has a nice clear dark “US”. Canteen cover and belt match very closely in color and wear. A very attractive set that has been sun/sweat bleached. $38.00"

"This is a real nice example of a war dated .45 holster in great shape. The date appears to be either 42 or 43, hard to clearly make out, but it is one of the two. The leather is in excellent shape, a small amount of verdigris that can be quickly cleaned. $125 plus shipping." [hasn't sold, and is in very nice shape CB]
