So, as interesting as the Vintage Motorbike thread is, I thought it would be of interest to some of you if I posted these pictures of a very rare Giffard Air Rifle. This particular rifle is 6mm bore and pneumatic, made in England (yes, really we were very good at this sort of thing) in or around 1870. For your delictation: The photographs show it well but in the flesh as it were it is of several magnitudes nicer. The finish is superb. graham. |

131 forum posts 12 photos | Graham, It's a wonderful bit of work alright, and although I've never seen a Giffard in the flesh, the case colours look all wrong to me, more like "applique" done with a cotton bud and hot blue solution and then torched, rather than the genuine article. I think it's been extensively refinished. Do you know it's history or where it can be seen? Eug

474 forum posts 202 photos | Lovely. This Giffard air rifle bloke.. did he invent the "Giffard injector " (as briefly mentioned in Jack Foremans "4 jaw work" thread last week) too ?. Another thing, how is a barrel rifled ? |

546 forum posts 32 photos | What a lovely piece. The colour case hardening looks wrong to me too, there are people who cheat and use a blowtorch (have a look on youtube) rather than the bone, leather and charcoal pack cch. What sort of power does this rifle produce ? A bit more than 12 ft/lbs i'll bet. |

Another pic showing the colour on the Breech Block. I do know the photographs have been "enhanced" in Photoshop but the colouring is genuine: graham. |

888 forum posts 36 photos | Ronan, an interesting question. I have access to another and if I get a chance voer the next few days I will put it over the Chronograph and find out. The chap who has it uses it regularly. graham. |

![]() 1243 forum posts 202 photos | Yes Graham a rare piece indeed and a delight to see. Personally I reckon the CCH is genuine, I've seen.a lot over the last 40 years and had quite a lot of guns re-hardened. The pattern is unpredictable and depends on many factors. One of the best outfits still operating is in Birmingham and their work is superb. Hacksaw, rifling is done in several ways, cut rifling, as its name suggests is cut by pulling a cutter through the tube, a bit more to than just that but it would require a long explanation. Then there is button rifling, done by pulling a carbide button through the tube. Lastly there is hammer forging, a process done cold on a blank the barrel comes out finished and chambered for the desired calibre. A very impressive process, incidentally some makers use this for shotgun barrels as well. |

546 forum posts 32 photos | I wouldn't be too harsh on the ordinary run of the mill british made airgun, they were usually of a pretty conventional design. A lad in the gun club has a collection of early (pre ww1) lincoln jeffries bsa air rifles, and later (up to the 60's) webleys. They are beautifully made and finished, very good quality walnut and bluing you can see your face in. Certainly not built down to a price. Great fun and cheap to shoot too. |

I believe he is one of the best in the world at cch, turnbull in america is supposed to be fantastic too. I have been told cch is not a trade or a science , but a sort of black magic. Some of the old gunsmiths had recipies of hardening compound that they would get good results with and would never reveal to anyone else. Maybe the magazine would do an article on case hardening , its an interesting subject, and its now more difficult to achieve seeing as kasenit is no longer available. One chap on an american forum recommends aquarium charcoal to me , anyone have any experience using this for hardening ? |

888 forum posts 36 photos | Thought these might actually be "on topic". The first picture shows a vintage Mk1 Webley rifle (quite rare) But underneath is a fully working model of a BSA Airsporter. I don't know what scale it was made to - if any but the barrel is a turned down .177 cal. BSA barrel. The two miniature pistols shown in the pic below are also interesting. The model of the Webley Junior in it's box is just fabulous and I just missed owning this myself. The present owner is a friend of mine and I have first dibs should he ever sell it. Again fully functional but you have to use cocktail sticks as ammo! The other tiny "Pop Out" pistol is a model of a Diana and I suppose most of us had a Pop Out be it Diana or Gat at one time or another. the other Wenbley pistols are also interesting, but only to an anorak like me graham. |

615 forum posts 21 photos | I had a Gat once, great fun it was. The muzzle velocity was so low you could watch the pellet in flight, and the way gravity caused the trajectory to droop at longer ranges. I have a couple of Airsoft replicas firing plastic pellets, they are better, a Glock 17 and a Luger. One of them is very inaccurate, but the other is quite good. My brother has Dad's .177" air rifle, I think its a Diana. The first time he taught us to shoot with it, he took along a plywood backing so we didn't endanger any sheep in the distance. Then we found out that the pellets were bouncing off it and coming back at us too close for comfort! We therefore tilted it back a little so they bounced off higher into the air, just as 'stealth' techniques are used to hide warplanes and warships from radar. Geoff |

157 forum posts 4 photos | When I was a lad, the Diana pistol was referred to as a "push and blow". Quite a good description of the way it launches the projectile I think. Gordon. |

![]() 6137 forum posts 893 photos | I had a GAT, couldn't hit a thing with it at more than 10 feet and it had a terrible range I managed to "improve" it by crunching up match heads into powder and packing them into the back of the slug The pin would ignite the slug upon firing and gave it a much better range, with the added pleasure that it looked like a tracer bullet as it flew off across the neighbours gardens Aye. Them were days |
