Well, I was thinking she could be number 20 since none of the other pack members have that number (On a side note, I personally think that Buster might be number 13). And I was thinking she could be based on a Aveling Barford grader. I'm not quite sure when exactly they started building graders, but I do know that that company was founded in 1934.
