Good for you, Vinnie!
Please ignore the identical question on your review page.
To answer Bradley's question, according to Jentz, starting in June 1944, a full company of 13 234/1s (with 3 234/3s) were issued to 6, 8, 9, 11, and 116PD, Panzer Lehr, Brandenburg PGD, 2SSPD and 9SSPD. Starting in January 1945, they were issued to 4PD (7 vehicles), Führer-Grenadier-Division (4), 25PD (4), Müncheberg PD (4) and Begleit-Kompagnie zur besondere Verwendung (no- I don't know who they were, either - 3 vehicles).
Other units who appear to have had them are 2PD (2), 1SSPD (5), 12SSPD (4) and Panzer-Brigade 150 (6).
On 16th December 1944, (if you want to do an Ardennes vehicle), you can choose from 2, 9, 11, or 116PD, Panzer Lehr, 1SS, 2SS, 9SS, 12SS, FGD or PB150. Spoilt for choice!
