pedro68 Posted October 3, 2012 Report Share Posted October 3, 2012 hi there , im trying to find out if my laurona eibar is a magnum and will it be okay to fire steel . so far i have discovered the gun was made in 1985 these are the markings i have seen on the gun and barrels ,can anybody shed some light on it for me. stamped on both barrels is 18.4 stamped on the flats of the barrel is 1460 gmos E2 on the underside there is FMN1270 On the side of barrels 1200kp/cm (i think) there are stamps CH also BP one like a knights head with a x under it and one i cant make out. Any help would be great. i went to my local gun shop but it was a rookie behind the counter but he phoned a gunsmith he knew , he just asked if the make if it was o/u and was it multi choke .then said it would be okay for steel as long as i used half choke or less.

mr williamson Posted October 3, 2012 Report Share Posted October 3, 2012 Im not sure so please dont take my word for it!! But i think 18.4 is the bore diametre. The 1460 could be maximum cartridge preasure in bar! The 1270 cod say 12/70 wich would mean 12g 70mm chambers. Or could be again preasure in bar, im abit of a novice on proof marks. But im always happy to try and help. Some one will be along shortly to give you a better idea Quote Link to comment Share on other sites More sharing options...
pedro68 Posted October 3, 2012 Author Report Share Posted October 3, 2012 hi there , it would be good if the 1460 was the bar reading, steel would be no problem . the 1270 is next to FMN i dont think that is the chamber size , the person i bought the gun from said he has shot 76mm through it and i think most laurona are 76mm.i think your right about the barrel diameters being 18.4. thanks for your input mate it all helps solve the puzzle .

wymberley Posted October 3, 2012 Report Share Posted October 3, 2012 Obviously, the proof marks are Spanish. The knight and the cross means the gun was proved at Eibar. The BP is nitro proof. the CH is suplementary or magnum proof as is also indicated by the 1200 proof pressure figure. the 1270 is 12 bore with 70mm chambers. If the bloke you got it from has 10 fingers and no visible scarring to his face/head, hes is either very lucky or telling porkies about the 76mm cartridges. Ignore everything that I've just said and take it to a qualified 'smith BEFORE you use it just in case the bloke was lucky - you may not be so.

pedro68 Posted October 3, 2012 Author Report Share Posted October 3, 2012 hi there ,thanks for posting that info, do you think i could fire steel from this gun in 70mm cartridges,i think il take your advice and wait until i get it seen to before i try it, i was nervous about it as it was .bloke i bought it from said it was a magnum and shot 76mm carts but i cant see anything on the gun to say that. if you say the 1270 is gauge and chamber then it seem its not . ****** now i need another gun for 3" carts and steel proofed for shooting on the foreshore .Thanks for your help mate.

old_n07 Posted October 4, 2012 Report Share Posted October 4, 2012 If the gun is steel proofed it will have the steel proof mark on the barrell Quote Link to comment Share on other sites More sharing options...
