Did the firm of Basse und Selve manufacture any other metallic cartridges than the 11.15 x 60R Mauser? Jack
I have a 6.5x54R cartridge marked 40,09,40,BS…Pete.
Pete: Excuse my slow response to your useful information. It’s likely that the letters “BS” on the 6.5 m/m round do indicate Basse & Selve, but as a metal source rather than as a case manufacturer. The letters BS are found on Dutch 6.5 m/m rimmed cartridges from at least as early as 1912 to your 1940 specimen. In this period the actual manufacturer of the cartridge case, the Dutch facility at Hembrug, was omitted from the headstamp but letters indicating metal supplier or brass lot number were present.
Other than the BS marking Dutch cartridges in the period 1912 to 1920 or so generally have a series of single letters of the alphabet comprising about the last dozen or so letters of the alphabet. The single letters I assume are contract or lot numbers for unstated metal suppiers; BS is (it seems) the only firm identified specifically. It’s interesting that BS would appear as late as 1940 because Basse & Selve had by that date become a part of the VDM metals corporation.
I have a Dutch 7.92 x 57R round (which I’d incorrectly identified as a .303 until put right this morning, thanks Jim!) with the following headstamp:
12 o’clock - 39
3 o’clock - 39
6 o’clock - BS
9 o’clock - 28
So having searched for info on BS this topic came up. So I’m presuming the BS is Basse & Selve and one of the numbers is the year of manufacturer (again presuming the 39 to make it 1939) but any idea what the other 39 and 28 indicate?
Perhaps this previous thread might help:
The Dutch called the caliber 7,9 mm according to de Vries/Martens, Nederlandse Vuurwapens, who use 7,9 x 57R for the cartridge.
There was no caliber given on the packages, only the designation “Scherpe No. 23” or “No. 23 S”.
Many thanks Sam3
JPeelen, Thanks for this additional info
