Hi Dave and a warm welcome to the forum. I hope that you find our archives and resources usefull and benefit from your time here. If you're a born again modeller feel free to share some of your experiences with us.
My experience with a very old Humbrol Airbrush was that it is really a fine spray gun. Having said that I learned a lot from it and, as it cost me very little, ended up owing me nothing. You will struggle with any sort of fine work but it is very handy for base coats and covering and you will always get a better finish from your Humbrol than you would with a paint brush.
Try it out as much as possible and get to find it's limitations. When you have done that you will be ready to progres to a proper airbrush and I am sure the likes of Nigel will point you in the right direction for a beginners model if that's what you fancy.
By the way is Dunmining anywhere near Dunroaming?!
