The cabinet looks well preserved if the speakers are in the same conditions as the cabinet then it's an awesome cabinet
The wiring is not original and there is a stick in the upper left speaker that says T/L. Don't know what is this.

I should leave this to Dr Hi-tone, but this is the same guy as the questionable amp, which sold for $1750. Same story as the amp. Apart from the wiring, No name plate, and fuzzy labels on the speakers. Also the wood brace, I am probaly off the mark, but even for an unoppened spaeaker cab, that wood looks fairly recently cut to me, and the rivet very new, when all the other bolts etc have a patina. Maybe the Dr has made me over suspicious. Seller has only recently moved into musical instruments, nearly 100% art before then. The cabinet is in the Hiwatt registry BTW.

That sticker will mean top left, but it is the top right looking from the front. I am sure I have seen that sticker or similar in the past

you are correct to be suspicious of this cab.
it may be a decent "Player" but, It is hardly anything special.

I feel bad for the new owner of that amp.
