I can't think of any, but archer dry transfers. They are not specific to the DW but are impressive on it. BTW Panthers were as big as the crew would go. More often than not, the DW crew wouldn't even put a Panther on the trailer unless it had a damaged suspension. You will see more pictures of the DW pulling a panther than having it on the trailer. But they puleed, dragged, carried everything underneath the panther's weight. I have heard a story of the DW towing a tiger without tracks on roadwheels, but have nothing to substantiate it, so take it with a grain of salt. It wouldn't have been over rough ground, I gaurentee you that. If you want a couple ideas, try a Cromwell or something Italian, or something free french. You never see anything about the other countries vehicles on the DW, but they were used to support both the British and the French if the need arose, I don't doubt they were used in the cleanup of Italy as well.
Also, get a lot of chain for it. It looks good with a lot of chain.

PS. I have two DW's and my mother is shipping me another for Christmas, so I have a few other thoughts on it.
