I wish I could help with a concrete answer but having failed to do due diligence for my own Saxon forces (28 mm Westfalia Miniatures, now produced by another company, I believe) all I can do is suggest consulting Peter Bunde’s The Saxon Army 1810 - 1813, if you have not already done so. George Nafziger also produced a book that one would hope might include the relevant information, titled Poles and Saxons of the Napoleonic Wars (possibly now OOP). If neither of these helps I can only recommend posting the question on a site that is wholly devoted to the period such as thenapoleonicwars.net.
