These traditional spyglasses would not look out of place in the hands of Nelson himself! Both models have four extendable telescopic sections and magnify a powerful 10x-30x.  The zoom is operated by twisting a control ring made of copper.  The Brass/Leatherette model is supplied with a soft zip-up case, whilst the Full Brass model is supplied with a very attractive solid Mahogany felt lined presentation/storage box.
