If it has the cap style forend and not the barrel band an 1895 45/70 forend will fit. This may help expand your search. If it’s the band style you’re out of luck unless you get lucky on EBay or something.
Try Boyds, Midwest,or Gun Parts Corp. In my experience Boyds can have some inletting issues you'll need to address with Accraglas. If you are a bit of a do it yourselfer Treebone carving can supply a good one you'd have to fit.
