Thanks for your reply. You're right, my explanations were not very clear. I compare the same measurement (mahogany body+outer edge height of the maple top). For example, Serial number 9 0663, which is Slash/Joe Perry's Les Paul that I wish to reproduce is 47,5mm thick at the end of the body (body + top). So I wonder if the mahogany body on that guitar is thinner than 44,45mm (1 3/4") or if the top of recarve of the maple top is less than 4,76mm. I know that I am talking about less than 2mm but I was surprised that all the measurements in the beauty of the burst were less than 49,21mm.
