Line
I used a new-old-stock non-tapered braided silk line which had never been dressed. One problem I ran into was figuring out what to dress it with, if anything. Most modern instructions on caring for silk line emphasize its use in dry-fly fishing, where the goal is to treat the silk line to prevent it from sinking—not as much of an issue when you’re wet-fly fishing. I finally decided to treat it with linseed oil only.
The following is from “Vade-mecum of fly-fishing for trout,” GPR Pulman, American Turf Register and Sporting Magazine, March 1842:
“The silk line too readily imbibes the wear, by which it becomes over heavy, and remains long wet, which causes it to rot speedily. On the other hand, the hair line is in general too light, and therefore not adapted for throwing against the wind; it is, also, from not being sufficiently pliable, apt to kink in using. [The author recommends a mix of both]... For ordinary trouting twenty-five yards of line are sufficient... It is not, we think, generally known that nothing rots horse-hair sooner than oil, which liquid is sometimes applied to lines under the mistaken notion that it has qualities of an opposite nature...”
The following is from:
“The majority of lines were made of a mix of silk and horsehair, but plaited silk lines were coming onto the market. The plaited line was an important development, because it was the first step on the way to water-proof, rot-resistant fly lines. The best lines were plaited from silk, and were thinner and stronger than their twisted counterparts, being available in lengths of eighty or a hundred yards. There was another, important development. Silkworm gut "casts" (or leaders, as we would call them,) were beginning to displace horsehair.”
“The use of horsehair lines began to die out after the 1860's and 70's, although the material still had its adherents many decades later. The difficulty of making long lines out of horsehair was a key factor in hastening its end. No longer did fishermen use thirty or forty yard lengths of line and hang on like grim death when they hooked a salmon; the development of the check, high capacity single-action reels, backing line and the acceptance of tapered fly lines meant that they could cast a long way and allow a fish to run. The braided silk fly lines had such a huge advantage over level horsehair that no angler who had tried silk once would ever go back to the traditional materials. Silk could be cast further, mended, and generally controlled so completely that it revolutionised fly fishing.”

For the leader and snelling the hooks, I used new-old-stock silkworm gut, connected with loops. The gut that I got was 10 lb test, but I think it would be better to use a lighter weight and build up the leader by knotting more sections together as needed.

The following is from “Vade-mecum of fly-fishing for trout,” GPR Pulman, American Turf Register and Sporting Magazine, March 1842:
“The lowermost part of the line, we mean that to which the flies are attached, is made of gut, and bears the several names of collar, foot-line, casting-line, and gut-link. It is composed of a series of lengths of silk-worm gut, which should be of good quality, and not, as it often is, the coarsest and worst... There will occur few cases in which more than four yards or less than two yards of gut will be required... At the point is to be fastened the stretcher--as the foremost fly is termed--by means of a knot, the same as that by which the lengths of gut forming the collar are joined. This is called the old angler's, or the slip-knot... As to the mode of fastening the drop-fly, the modern neat and simple plan of inserting the gut to which it is attached within the slip-knot of the collar should, and doubtless soon will, supersede the clumsy and inconvenient loop. Many anglers are in the habit of using more than three flies at a time, a practice which we by no means uphold... Instead of connecting the line and collar by means of loops, as is almost universally done... “
