OK, it has been about 30 years since I made these, so I had to look up a few things. Hopefully Hawkeye2 will help jog my memory, if I miss something.
I don't recall there ever being a DIY pattern for these slings, but perhaps the following info will help you out.
First question I have is do you want an exact copy of a period sling? The reason I ask is because you have to buy or make the brass sling hook, if you do. I used to buy original excavated ones when I made my repro slings, but I doubt those are available anymore or the price would be too high. Looking around at the repro hooks, this appears to be the closest copy to the originals, but it is a little different:

here is the other one normally sold and it will work, but I prefer the one above:

The original hooks were held on the leather by Brass rivets and burrs (washers), but it seems most of the repro hooks are made to use brass nails and they don't include the burr (washer). I used to be able to walk into the GREAT old fashioned Fredericksburg Hardware store and buy the correct size rivets and burrs, but that store and the even slightly better Pleasant's Hardware in Richmond have closed down. So if you want to use them, you would have to find them elsewhere and I'm sorry I don't remember the correct size. Here is a photo of a copper rivet and burr to show you what I mean, though the originals were Brass:

Now as to the description of the sling. I'm sure you would prefer it out of the Confederate Ordnance Manual. :wink:
GUN-SLING (russet bag leather) - Width 1.25 inch; length, 46 inches; 1
standing and 1
sliding loop;
hook (brass), fastened to the sling with 2
brass rivets No. 15 wire.
The
standing loop is the one sewn to the end of the sling. Many if not most repro slings made today are 48 inches long. However, you have to start with a longer piece of leather to make the sewn folded over end that holds the hook in place and is tapered down towards where the hook comes out. That folded over end may be seen in a zoom close up in the following link. (Oh, please also note the good sewing of the standing loop. Some repro slings have horrible looking staples instead of being sewn or the sewing is, at best, amateurish or downright sloppy.)

The Ordnance Specs don't say how wide the loops were, but I think I made them 3/4" wide. You can make them wider if you wish. I have seen original loops that were butt sewn or sewn with a curved needle flat end to flat end OR others were sewn similar to REAL M1903 slings with the leather ends folded over each other and sewn through both folds. BTW, I know it is not exactly by the book, but I have found I prefer at least one more sliding loop on my slings - one to hold the hook in place and one closer to the front sling swivel.
OK, I am going to end this post because we have been having intermittent power outages and I don't want to have to type this post again. More coming in Part II.
