Vintage Seth Thomas Adamantine Mantel Clock MODEL "Durban" c 1904

I don’t know much about Antique Mantle Clocks, but this is Vintage Seth Thomas Mantle Clock with Chime. I searched 3,067 Antique Mantle Clocks on the Web and only found one like this one.  If you know exactly what it is I’d appreciate if you’d email me and let me know. I believe this is a Seth Thomas Adamantine Mantel Clock called the "Durban" which can be found listed in Tran Duy Ly's "Seth Thomas Clocks & Movements" Third Edition Volume 1 page 447 (Clock #1462). It is circa 1904 and originally retailed for $7.60, which would be about $255 today. This clock is in very good condition, however it only runs for a short while.  It will likely need some maintenance and adjustment after many years in storage. The chime works great and it “dings” on the half hour.  This is apparently a very rare model.  In 2005 Tran Duy Ly appraised this model at $375 and it has actually appreciated in real value over the years. It should be worth about $550 today. There is a small hole in the top that appears to have had something glued there.  The key is broken and there is a missing screw in the back and the back is cracked.
I make no claim as to the originality of key or pendulum.  I will package this clock with extreme care, you might check out my feedback in that regard.
If you know I have made an error in this listing, please do me the curtesy of telling me so.
I have no intention of misleading or misrepresenting here.
