It's apparently not THAT rare, although admittedly still scarce...... I've owned about 8-10 over the years, between upgrading etc.... and have found 4 or 5 of them...... All in varying condition, from a well worn good to a nice EF+ (US grading standard)..... Much like the F-14, Scarce but not rare....I've also owned about 8-10 of those, and have found all but 3.......
