Am in the process of sorting an estate collection, and ran across this carbine. Thought I might post some pictures of it. Have also pulled in this quote from DocAV that seemed relevant. Enjoy....
I can't get the Photo, but some "Kar-88--7mm" (Haenel M1907) were bought/smuggled into Mexico during the 1910-1920 revolution.
It would be idiotic for getting them in"8"mm. as ammo would be hard to come by, whereas 7x57 was the Mexican national standard.
Supply of clips could have been a problem...unless a large batch came with the carbines...or even a large batch of DM export 7mm ammo already in M88 Clips.
BTW, the M1907 7mm M88s were readily available from Hamburg Outfitters ALFA and AKAH, besides direct from Haenel prior to 1914...maybe even some got over to Mexico during WW I...Neutral shipping from a neutral Port, such as Spain or Portugal or Holland/Skandinavia. It is known that goods were allowed transit to some Neutral countries out of Europe by the Allies ( ie...Switzerland to Spain ( across France in Sealed Railcars) and then onto to mexico, or via Sweden or Norway and onto Mexico. Since these were classed as "sporting Goods" they did not have the restrictions of "Military Contracts"...and so could pass, in small quantities, unobserved..... .....An interesting subplot to the Mexican Revolution.
