The Mallard

Hi all Not sure if I am doing this correctly, so please guide me. I did a little research and it brought me to this site. My father passed away and was a huge steam engine (mainly South African) enthusiast and the plan was to send his retired life building models. Sadly cancer got the better of him. We did have time to go through some items, so some I know are extremely valuable. My question is where do I begin? Are the model railways specialists out there that can come give an honest evaluation for auction. I am hesitant to place it on Ebay, coupled with the fact that there are masses of items. Amongst all of this are a huge amount of electronic items too. Hope to be advised wisely :-)
