This concept came from the marking on the books, as we told above, when we read any book, it happens that we can’t it at once, so we fold or mark the last read page to remember where we left the reading. Sometimes taking parts from one brand and fitting them to the acquired parts often these were used to fill Hardware" gun contracts.like a manufacturer making guns for Sears with the JC Higgins name stamped on it(or anyone of a 100 other store names) Over the years i have found a number of utility grade entry level product made ffrom a mix of parts.the grips you discribe being on the wrong brand may even be an example of that.Bookmarking is a way of saving URLs of the visiting websites or web pages for future visits on them, this helps us in saving URLs in the browser, so we can easily find and visit any previously visited website or pages. This led to quite a few hybrids being assembled and sold.The company that acquired one brand label would often use what shelf stock came with the purchase and continue to assemble guns until these parts ran out. These companies made guns.then dissolved or were acquired by other such manufacturers. The book is available from FWIW, It the prime of this type of inexpensive revolver, there were many companies producing the same basic gun. and ammuntion A book which cites all sorts of trivia about firearms proofmarks M-14 production Luger variations etc etc etc.You can find the grip logo info on pages 232 to 234 the title of the grip info bears the word "SOME" indicating that it is nowhere near a complete list. in a circle for the Iver Johnson Arms and Cycle Works The data I cite is from the Joe Vorisek book titled A Basic Guide To Old Firearms. of NY There is still anoth H&R pattern that contains the head of a dog(the screw is in the dogs head) The IVer Johnson grips have an OWL as its centerpiece and another is the U.S. There are also some grips that bear the H&R logo etc and attributed to both H&R and to Malty-Henley Co.
The 3rd design.for lack of a better term appears(to me anyway) to be similar to pin striping used on custom cars and bikes I see no particula picture just a highly decorated mushroom like pattern with what appears to be a bullet shape encompassed into it. H&R used at least three different markings on their revolver grips Besides the one you discribe, they used a shield with stripes(dark and light alternates) with a semi-circle spanning the top with a solid star enclosed in that. As you said the grip with the square set in a cricle with the target and bullet holes is a H&R part If those grips are on a Iver Johnson revolver, someone needed grips and dug around until the found a usable set and retro-fitted them to the gun. If IJ guns are your passion.you might want to check out the late Bill Goforth's book on IJ from title IVER JOHNSON Arms & Cycle Works Firearms 1871 - 1993 If you want it quick there is a fee service that does this If nothing else check this website to see what they need to make an ID.I need at least that(I'm dumber) You post it here or send it in a private message and I'll do a search. If you can supply me enough data to ID the exact model,I should be able to date it for you. each of these is further defined by 1st model.2nd model.3rd model etc. In the Tpo-Break there are Lovell Hammerless Automatic 1886-1889 (btw "automatic" refers to the case extraction) Lovell's swift models 1890-1895 From 1894 to 1940 there are some dozen or so variations Safety Automatic hammer revolvers.Safety Automatic Hammerless Rev.
On some modesl only the letter matters while on others the letter and the serial number are used to determine a DOM Also.the markings EXACTLY as they appear and WHERE they appear are important There are even some that were designed and made by other members of the corporation (like Lovell.Johnson & Bye Iver Johnsons Arms and Cycle Works.Iver Johnson Arms etc) Some are even difined by gripo shape like Square butt models.Birds Head Models Al, IJ used specific letter and numbers on specific models of IJ Top Breaks.both by sub model designation but also by caliber and if it is a hammer gun or a hammerless gun.
