Serian wrote in Holmes True 1st difference?:I recently picked up a true 1st Holmes pretty cheap (F115-R, blank bottom)Examining the box, there is the F115-R designation on the "top" edge as well as the front cover.I've never actually looked for the product code there before, and my other 1st print Holmes is away in storage.Is this unique to the true first or is it on all of them?
