Porter cable crown stapler

How I came into owning these my husband tried working again, things were going well for him installing cabinets and trim and such. He had work for about a month out. One job was for friends whom we trusted and it made sense to leave his DeWalt trim guns at their house for a few days while he was working on a landscaping job. He finished early on that gig and then was asked to install and trim some cabinets for their garage. Driving to the other job did not make sense as it was far away so he ran to the hardware store and picked all three of these pneumatic guns. They have only been used on one job and are in excellent condition. They worked perfect until he got his DeWalt stuff back and have been stored safely ever since.
