Here is a 1995 - 62050 Tan Rogers bone - Bomb shield - 72050 main blade with back side of main engraved " Prototype " that's pretty rare as most of these 95's were burned up in a fire at the factory!
1994 - Red Rogers bone - back of main blade is etched " Pre Production Sample, Hand Made " - front of main has the " Elephant XX Elephant " etch - Arrow shield - serial #00.
1994 - 52050 Genuine Stag - has 1 of 12 main blade etch but is not mentioned in the Case Classics book with the Bowtie shield. This Elephant Toe 2050 pattern was shown to Buzz & John Adams of the Case Classics club & Roger was told that it is ultra Rare & may be an unmarked " Prototype ", the only 52050's that were made with this 1 of 12 main blade etch had the Arrow shield & not the Bowtie shield!
