once you have all the pieces together, and if its possible erect it,..which might be difficult..or easy, it all depends on...if you,ve got a space big enough to accomodate it...and then...get someone to identify...what wood it is on the face...the bones of it will almost certainly be pine...but the facia will be a mixture of quality hard woods...get as much info as possible...i.e. what church it came from..if thats possible...then...a dvertise it world wide...
good find and good luck....
