No 6 SHEFFIELD STEEL 22cm Indian Shell puller lever Brass & Horn vintage automatic knife

Vintage No 6 SHEFFIELD STEEL 28cm Indian Shell puller lever Brass & Horn automatic knife made in India sometime between 1930 & 1960s using stampings (markings) copied from English knives that they had seen. This knife has shell pullers built into the bolsters supposedly for extracting shotgun shells from old shotguns, but I don't think these are actually functional, just decorative on this knife. It measures 22.2cm (8.75 inches) open and 4 7/8 inches closed (not counting the pullers) with steel liners & pins and brass bolsters & lever. The spear point blade is 98% full, or better with patina light pitting and some spotting and says SUPERIOR STEEL on the face of the blade below the spring with No 6 SHEFFIELD STEEL stamped on the tang with two Footed Crosses on the reverse. The horn scales (handles) are in good condition with a couple of minor dings from handling/use. The knife works well with blade tip 1/8" above liners closed (peeks), good snap and good lockup with about 1/8" movement at the tip. Rattles slightly when shaken open.  G+ condition.
