I'm presently rebuilding and restoring the bed on my 46. After I got it all apart I found that the two middle crossmembers were bowed or arched down a bit and was wondering if this is normal for the Art Deco series or is it from carrying loads over the years and has anyone seen this before. I imagine they should be straightened out or the boards won't line up properly and when bolted in there would be a depression in the middle of the box. I'm thinking of using a hydraulic press to straighten them if they need to be. Any info would be appreciated. Bob T
