I just purchased a "Schrade" Uncle Henry" 897. I don't have the knife yet but, from the seller's photos, it appears to have: 1.single pin, 2. pivot pins barely showing in the bolsters and, 3. clip blade tang marked:Schrade+USA, 897UH So-there goes my supposition that Camillus-made Uncle Henrys had tangs marked SCC (or at least that ALL of them did)! Any thoughts? Thanks.
