Nautilus
Here is a 12inch Nautilus that I found on the south coast near Lyme Regis. It was basically covered in about three inches of limestone matrix most of the way round. It was quite a long prep this one taking about a month doing the odd few hours here and there in my spare time. I prepared this mainly using a Pneumatic Air scribe model ST commonly called an arro pen, I have two of these pens the first one I bought from Ken about seven years ago. I now have a model HD as well which would have been a lot quicker on the job.
Nearly there not much more to do now just a couple of small repairs.
Working away merrily in the sunshine.
Finished Nautilus on my sideboard.
