What happened to Sub Caliber Runway inserts?

 I got a plastic 22 lr barrel insert for 26.5 mm flare guns, not metal one by Runway, I got a 45 Long Colt/.410 bore Runway sub caliber barrel insert and noticed Bud K and Kennyhal discontinued firearms related items like Bud-K, does anyone know someone who has a USED Runway 38 Spl barrel insert for 26.5 mm flare guns? or if they are discontinued due to firearm related items being so far in demand for all things even ammo costs are unreal how hard it is to find anything due to Covid pandemic caused severe back orders and some manufacters cannot get all the orders delivered in one year backed up that far. Anyone know who has 38 special runway 26.5 mm flare gun insert please comment below. I highly recommend them, I tried finding one used one for 38 spl and nothing shows on internet due to backed up orders and so much demand.
