He has a large database of official as well as unofficial Royal Navy badges. In fact, he estimates that has in excess of 1,500 badges to choose from! Many of these badges are also available in different sizes. For example, Hood's badge is available in 5 inch, 7 inch and the 5.5 inch "tampion" sizes.
So, if you are interested in obtaining a Royal Navy vessel's badge, whether official or unofficial, please contact Dave. Based on your requirements, he can then tell you the availabilty, size, shape and cost. The price for all badges is £25 (the only variable is the postage). His work is excellent...just look at the sample images below!
