There was a question about did Ulans wear numbers on their uberzugs? The answer is, yes but rarely. I have just gone through 250 Ulanen photos in the period Photo section using a link posted by PickelMax. Out of 250 photos which did include many pics without "covers", there were 9 that showed numbered uberzug being worn. In some of these, only one man would be numbered while standing in a small group, the majority shown in these photos are wearing plain covers. Here is a list of the 9 Regts that showed numbers being worn: 4, R53, 3, 9, 13, 10, 16, 2, 17. The R53 was R over 53 but I can not type that. In all my years of collecting Ulanen uberzugs are rare and I have never seen one with number(s). I had one in my collection but sold it, I have only seen examples posted by 4-5 other collectors.
