Just by the cut of the bucket, and the texture of the pigskin... I'd guess the pig holster is an erg code.. Seems the more common, and most of the time best condition ones are DLU code.. they are usually not all pigskin either. The straps and spare tool pouch may be made of cow hide or pigskin. A nice supple "pig" holster in that condition is really, really, really rare!!! I'd have to see the inside and the back, but if it's like the front, I really don't think $750.00 would cut it! (Sorry Pete! ) If anyone has some like this for sale, "I'm your huckleberry" As said by Val Kilmer in a Wyatt Earp movie! Especially DLU types... Leon knows what I mean!
Best to all, til....lat'r.....GT
