Yes, Mickey,
my sights work for windage and elevation. My suggestion to the many gunmakers I tried to sell it to was that they could more-or-less mass produce db rifles, trying to guess the barrel separation required. Those that worked could be tarted up with engraving and classic sights and sold at a premium; those that did not could have a fixed sight backed up with my sights for longer distances and be discounted slightly. Obviously, while H&H and Purdey could maintain their mystique, flogging rifles for small fortunes and lifting the price cheekily every year or two, they were not going to go there. I did get a nice collection of letterheads, however.

If anything, I discovered that regulating barrels may not be the big deal we were always told. Paul Roberts at Rigby told me they only made about five rifles a year but he could regulate several in a day.

Martin,
if you go into the Google website you will find a category devoted to patent searches. If you then type in 'alternating rifle sights' you should find mine at the top of the page. In there you'll see postage-stamp pics of about a dozen drawings, which show various versions. Click on the pics and they'll fill the page. Pics of the actual sight would not help you. Not being a gunsmith or mechanic, I only ever made a rough prototype of the first, the reciprocating version, which worked on my shotgun. The others are obvious as their mechanisms are less contentious and the patent inspector found no problem with the drawings.

In hindsight it was a waste of time and money but I had a bit of fun. I also gained a certain respect for both Browning and Roberts for the way they did business.
