I have been shooting recurve bows since late 1969. I used only Bear products for most of those years and I have never seen a 4 fletch factory Bear arrow.
The crest on the arrow in the pic looks like a Bear factory crear similar to many I have owned and seen.
Problem I see is that I only 3 feathers on the arrow in the pic, and, they are all natural barred.
I may be wrong, but I don't believe Bear produced arrows without a distinct 'cock' feather of contrasting color(s).
