Unfinished fake?
Its a pretty early chip. Oldest known Pentium Pro are from week 41 1995 and this around 10 weeks younger.

On the other hand, why remove the logo print?

oh.. many reasons... recall a certain member of this forum who removed the logo from a ceramic gold top ES pentium with wire wool. Genius. |

test it on some modo.....if even not heat its empty for sure...maybe its just for show-purposes on some intel event 
maybe is an attempt to fake it...
who knows.... |

Very interesting!! I think this is a special PPro sample.
100% of the blank Pentium Pro's I have seen have a engraved number in the bottom right hand side of the ceramic that starts with a E. There was one from Europe that started with a different letter than E but still had the markings in the bottom right hand corner
Also all of the very early Pentiums Pro's samples with markings have the same engraving in the bottom right hand side. Here are examples of both.
The blank below is supposed to be one of the first 50 Pentiums Pro's ever made and the Q0755 is the first documented Pentium Pro Qspec.

Do you have a link to the documentation for Q0755? |

The production date of the blank (Week 43 1995) is the eariest I have seen so far 
From the Pentium Pro time line i presume they are early 166 or faster Pro samples, as they were produced after production 150s were released.
I have been wondering.. if they were thermal samples.. why would they have a die date code 
EDIT >> checking production codes on the base of Pros.. my belief that it is an unmarked 200MHz 256k ES.. so should be fully functional
The additional code etched into the top of "Samples" & early ES comes in 2 formats... Exxx-xxxx or 1xxx-xxxx
The codes starting with E only seem to appear on 256k Pros
while the codes starting with 1 appear only on 512k Pros
These codes are likely put on initially.. with the part number & qSpec put on later as n when they are required
so ur blank most likely would of ended up being a 256k Q0861
and Jacs blank a 512k Q0865
