<p>[QUOTE=&quot;Francisco G Kempton, post: 4373718, member: 22714&quot;]Right we are in the antique catagory now. That is certainly gilt geso. That reddish clay is Bole. The sofa has been upholstered from the number of nail indentations in the wood and it seems over many generations. The nail in the back even looks old, maybe pull it out and see if it has a rectangular shank.</p><p><br /></p><p>That would make it pre 1890. Machine made nails from 1810 - 1890 had rectangular shanks with round or T head, the only machining was shearing the shank from the rod and the head of the nail had to be made by hand, So machine/hand made nails 1810 -1890. Prior to 1810 nails were forged entirely by hand and had square shanks and so the head was meant to be be round but would resemble something more like a cauliflower or a squiggly imperfect round.&nbsp;&nbsp; </p><p><br /></p><p>Post 1890 all nail were fully machine made and had round shanks and perfect round heads.Sheared rectangular shank nails are still made today as are t head nail used for flooring. If you can imagine a floor nail. In furniture however, the nail tells a more accurate tale. Also if you find a shank hole in the wood and no nail, there is another way to tell if the nail that was there was old, is the shank hole round or rectangular or square. Then if that doesnt work because the same hole wa used by a more modern nail, and since removed, you can tell by the dark carbon coloured rust left by old nails. That dark rust stain around the shank hole indicated an old nail, while brownish reddish rust indicates a modern nail i.e post 1890.[/QUOTE]</p><p><br /></p>
