Hello Tadumac,
I just read your burst above. I have also sought to have them cleaned up and repaired professionally but I am afraid the cost is prohibitive. I intend to do a very careful job and repair and clean them myself. One of them is worse off than the other as I came off the wall in a thunderstorm here that shook the house. I have heard that rubbing the pieces with fresh bread is is used by some conservators, and another method used by museums to clean oil paintings is using a cotton tip wetted with saliva. Sounds unusual but apparently it is a method that is used in most museums throughout the world. I have used a cotton bud dipped in white vinegar in a trial area of the background and this seems to work well getting rid of the grime with no effect in the actual paint
I will have to do some repairs on it and have sourced an organisation here in Australia that appear to be very helpful. If anyone wants fittings etc, I really recommend that that tale a look at the following site.

I will keep you posted on my progress as I have no intention of pushing it and making a mess of it.
Also I am trying to get some more history about my ancestor. The background painting is remarkably similar and both makers were sailors. I believe that his name was Johnson. You never know.
Regards Mark T
