My fiance and I are getting married in Aug and are having a bike themed wedding. We want an older, vintage tandem for our engagement photos and to have at the wedding. We've been looking all over locally (Salt Lake City, Ut) and are running into dead ends trying to find a bike. We want a good bike that we can use for the photos but we want something we can fix up together afterwards as a shared hobby/project.

We came across a tandem at a local antique store this weekend and the seller wants $300 for it. He says its a Schwinn but the geometry in the frame doesn't look like any Schwinn I can find online. We offered him $150 for it and he countered at $195.

Can anyone help identify the year, make and model of this bike so I can realistically know what I should pay. It would also help with finding parts if I knew what it was. Any help is greatly appreciated.

Pictures can be found here, Tandem bike - Imgur. Sorry for the potato quality. Its in an antique store and there was hardly any room to maneuver to get it into frame.

Thanks in advance!!!
