Unfortunately I have some bad news.
During the spring sale I got two (yes two) of the Brebbia Jumbo Bulldogs (I've been looking for examples of that pipe for years).
They're a bit underwhelming.
They both have nice round bowls and square shanks, but the buttons aren't quite level. Maybe a minor complaint, with an hour of filing and sanding I can re-square the stem and shank with the stem twisted a few degrees for a better position.
Worse than that though is that both pipes are lop-sided, one has the shank lined up with a point about 5mm away from the center of the pipe, the other is about 6mm off. I think these are the first pipes I've ever seen with a shank that far off center.
My old Pot shaped Brebbia Jumbo is just about perfect in this regard, it sounds like someone had a bad day.
Lastly, one of the Bulldogs had the mortise filled with putty to accept a smaller non-filter tenon when it's pretty clear that they were both drilled as 9mm filter pipes (I generally like filter pipes but it's not a big deal either way). I'm not sure how to feel about the putty in the shank, theoretically it should help prevent the mortise from swelling out of shape and I might have a more durable pipe, but I really have no idea what effect it will have in the long run.
There is also a noticable fill on one of them. I'm not picky about fills either, but this pipe has one.
I'm not going to try to return anything given that sending anything back would cost almost a third of the value of the pipe itself. Both pipes should be as functional as any other pipe, it's just amazing how "hit and miss" quality control can be.
I certainly don't blame people for wanting to personally inspect every pipe they buy.
