Yes, TOW & Tip Curtis have some hickory rods & much more worthy of your rifle. My experience with the dowel rods is they don't make good RR's. I would trash the fiberglass rod as they will wear the muzzle & you will end up cutting off 2" of it in a few years. If it is teflon type rod it will not wear as bad, but hickory is the best.
I also I suggest drilling the vent out to .0625 If it is a removable vent, you can cone it on the inside & outside sometimes & improve the performance. You need to keep a .025 straight wall thickness between the cones. The cleanest powder to shoot in the .32 is Swiss 3F & you should back your load off 20% as it is a Sporting Rifle Powder, not like regular BP. But a very fine powder, very accurate & clean burning. Also if you use a liquid lube such as Lehigh or homemade moosemilk rather than grease types you will have less fouling in the small bore.
As for the flints, it probably uses 5/8" flints & you can get Tom Fuller Black English Flints in that size from October Country. They are usually a little cheaper on flints than most. I buy them in bags of 100 from the in 5/8, 3/4, 7/8 and they are a considerable savings. Once a year they have a "Flint Buy" and that is when to get the quantity.
