Home & Garden Looking for OLD wood

We are working on a small project in a new house and am looking for OLD wood, like over 10 yrs, or from old houses. Width variable, can join really old pieces, even partial appreciated..... Approx:
2" x 12" x 12' - 1 pc
2" x 14" x 8' - 4 pcs
3" x 3" x 10' - 1 pc
2" x 14" x 10' - 2 pcs
2" x 14" x 14' - 2 pcs

 

I would imagine you would be hard pressed to get a board that would be 14inch in width and this would have to be made up in two or three boards if you could do a tongue and groove joint between the joining surfaces of the boards with a router and use epoxy resin as a glue, this being a filler glue that does not need such firm clamping.

Hope I'm not trying to teach my Granny how to suck eggs here?

Btw, I have a Triton Planer thicknesser available that does up to 12 inch board, this is not heavy duty but does a good job if restricted to o.4mm on each pass.
