Short translation, please?

Could someone help me with this translation, please? Any help is much appreciated!

Aún si fuera manco vería la forma de echar la mano.

Literally: Even if (I, you, he) were one-armed .... would see the way to put out a hand.

I think it would translate as: Even if he only had one arm he would find a way to lend a helping hand.

Thank you! Very much appreciated! :)
