I have a collection of Hill bows and I would like to know the distinguishing characteristics and/or stamps used by Tubbs & Allen. I want to add these 2 makers to my collection and want to have some degree of familiarity with their output while at Hill. I have 3 Tubbs bows made post Hill which are pretty easy to spot but I'd like to know if his production while at Hill had any other telltale characteristics. I also have bows made by lesser former Hill makers (e.g. Bultitude, Watson) which don't compare favorably to Hill makers such as Yeoman, Napier, etc. (IMHO).
