"As others have said, Phong is a hit-or-miss affair."
Imho most of the characters we have to deal with in this goofball hobby are this way. DW for instance. In my experience Yuki seems to be the most consistent and reliable, not the highest grade maybe, but dependable. Otoh, I have a Phong 1655 case from 4 or 5 years ago that is first class but that is the only Phong case I ever had.
In general, if someone wants something done right...they have to learn to do it themselves, dbane bevels for instance. I say this because anyone who wants extraordinary work should not expect it from someone who turns out good work one time and shoddy work the next. Frankenstein builders must also come to terms with the fact that they can not make a genuine watch using replica parts...case, dial, and bracelet come to mind, not to mention clone movements. The watch may appear to be genuine but it is not, and in reality it really makes little difference until it is put up for sale. Otoh again, I have noticed many posters on the 'Serious Collector' forums (VRF etc) are getting more suspicious every week and are not as sure as they used to be in knowing if their precious vintage watch is 100% genuine or maybe only 90% genuine because the lines are rapidly getting blurred by higher quality replica and generic parts.
edit 8-6: "So this man ask $$$ for random bad cases..."
Anyone could see those shotgun barrel lug holes from 2 feet away. When someone worries about one of their projects with a $200 case not being as close to genuine in appearance as they would like...just remember $1200+ cases can turn out to be like this one.
"Also, the lughole locations can be somewhat inconsistent."
I find this in replica cases from many sources. I have to resort to curved spring bars, reshaped hood tops, inner tubes being removed etc...it's all hit or miss. That's why I bore lug holes to 1.3mm...so curved spring bars will not be in a bind.
"maybe this is the way they come from vietnam, where I suspect his factory is."
Probably. I wonder if this is where Yuki cases come from?
I'm pretty sure DW cases came from J C Whitney.
