Sorry. I don't have one for you but...Funny story.
When I bought my Chinese SKS at Woolworth's in CA the spike bayonets were removed because the ATF had come in and said they were illegal. They had a whole box of them on the floor under the gun rack. They wouldn't sell me one.
Later at a gun store I was looking through the bargain bin and found a really clean cruciform SKS bayonet, I asked the counter guy how much the SKS bayonet was and he said "That's a tent spike". I said, "No, it's for an SKS. How much?" He replied, "It's a
TENT SPIKE and those sell for $5."
Ding, ding..the light went off and I told the guy "I think I really need a new tent spike"
Receipt said..Tent Spike $5....
