Golf club has fish symbol instead of number?

[jamhed]

I have dug up an old Sam Snead branded golf club and can't tell exactly what number club it is, as the only marking it has is a large fish symbol engraved where you would expect to see the number.
Anyone any idea if this an old traditional name for a certain club or something like that?

That's the club you hit when you have to 'prey' that is going to get the ball where it needs to be.
