I tried to give these ones to the police but they didn't want 'em so I kept 'em. I'm not complaining

I've been looking for a non-suspension-mtb for a while... Just hope this won't be to small... I'm not sure what I'll do with the other, maybe give it away...
The mtb is a Merida Dakar with Altus-gearing (completely ruined by rust though) and that makes me thinking that it's high-end. I found it in the wood where it have been standing for some years (my friend saw it about two and a half year ago but I couldn't find it back then). The gears, brakes and crankset are ruined by rust, the frame filled with water and the handlebars is bent. Hope the frame is usable...
The other bike is a Union - flamingo sport. A very good-locking frame with nice patina. Sadly the bike was run over by a car and both fork and wheels are ruined. The rest of the frame seems straight though!

I'll se what to do with it. Maybe I'll just use the brakes and handlebars.
Would be nice with info about the frames if anyone had any

(no need, could go through Google but it's harder and I won't get as much info)
EDIT: The brown stuff on the Merida-frame is not rust, it's aligers
