Pig pneumatic tattooer GILT’S BACK

Design to tattoo the herd number at the croup of the gilt just after they are inseminate for the first time. The idea there is never to lose the gilt ID's number even though it loses its ear tag which happens frequently with free sow management. Character size is 15 mm, which is perfect at that age to be sure that it will still grow a bit before the end of the sow's career. A source of compressed air acts a piston where a character holder is screwed on.
