    I have always desired a Seth Thomas Adamantine for my collection and my birthday was a good excuse to acquire one. I really loved the Larkin 35's design and of corse Ebay was accommodating. However as we know, years of temperature shifts as well as environmental impurities and time will cause the celluloid covering to out gas and create a milky or dusty grey appearance to the surface. The clock I found had minimal to no collateral damage you know Dings deep scratches etc and I was not concern with the condition of the 89C movement because I would completely overhaul it. So here are photos of the larkin No.35's progression. The first few photos show the condition of the celluloid surface.

    I Have found that the only way to remove the surface corrosion is with good old gentle elbow grease. the next few photos are of the finish product.

    I used what they called a micro mesh kit. these kits are used to restore plastic Aircraft windows and the nice thing about the kit is it is reusable. The sanding medium starts out at 1500 and goes all the way up to 6000 it is a wet sanding process. then I used Novus 2 fine scratch remover and completed the process with Mothers Show wax.

    Beautiful work. It's really amazing to see something that most people would write off be brought back to such a like-new (or better) state.

    How did you do the incising?

    I struggled with what i world do. I thought a first, i would use gold leaf. However sizing spillover on the surface used to adhere the gold would be to harsh on the old Celluloid and very hard to remove with out causing damage so i settled with Metallic Acrylic paint.First I made sure that I finished waxing. Using a very sharp scribe i carefully cleaned the scroll work and then by hand i gently used a drill bit for the little dots making sure that I only removed the little bit of wax in the scroll work. I then Used a very fine brush to apply the metallic Acrylic paint. after maybe 7 to 10 mins. I dampened a blue shop towel and began to rub the scroll work. It cleaned up extremely well due to the wax on the celluloid and left very clean lines. I have to say I was very happy with the results.

    Beautiful job. I love the look of that model too, and yours is certainly worthy of a place of pride in your home.

    Beautiful work! Congratulations on your find, and thank you so much for sharing it.

    Attached is a copy of a 1909 Larkin catalog page that includes this clock - given with 5 Larkin certificates or $10 of Larkin products. It was likely offered in additional years, but this just happens to be the catalog I have.

    Thank you both. I have never seen that advertising. Very cool.

    NAWCC has always been the one source in my research that has never let me down, and if in some small way through my postings I have been able to contribute to that knowledge base. Well then I'll raise that whisky glass and say cheers.
