One of my favorites

Roebling Twin Alligator Wrench. I am partial to alligator wrenches and this is only one of my many favorites. Sizes #1 and #2 on a 10" wrench with really good teeth.Made by J A Roebling of Trenton, New Jersey of Brooklyn Bridge fame.

I have one of the single end no. 2 Roebling's but have never seen one of the doubles.

Were they intended to be used only on square nuts?

[Papaw]

They were used on other fasteners as well as being used as pipe wrenches.

[Plyerman]

Nice one! Any idea on how many different sizes they made?

[Papaw]

I don't know what sizes Roebling produced. Others made up #5.

[Plyerman]

I must be dense. I never realized there was a standard numbering system for alligator wrench sizes. 

[Papaw]

I don't think there ever was.

[rustcollector]

Roebling made a #5 also, I have one, or had one.

Are these Roebling wrenches very rare ?

[Papaw]

Not especially rare, but when in good condition, they are beautiful to me!
