I never asked him where he got it from Maty,we just chatted about friends who live in the area,I will ask him,they got a turtle this morning anyway,not big enough to make a guitar from however
The elastic is just flat-band mate,locally made,most of the hardware stores stock it,theres three types of speargun in the pics,and theres a close-up of a trigger,they are all hand-made,I have seen small kids with tiny ones that work.
