This is the first French cert d'add, to French 385744, and reference is made to a Belgian patent taken 23 December 1907, the date of which differs, but the contents resemble the only 1907 material have on Wunderlich, that is, Patent BE-1907-202697. In fact, given Belgian speed of filing turn-over, and given the number of Belgian "perfectionnements" to which these French certificats d'addition make reference, this thread likely does take us back to Patent BE-1907-202697.)
