That is useful information, Oesho. Thank you. Needless to say that I have neither of those references, but I may be able to get ONS N/L 151 from Peter Smith. Anyway, I'll try. The NSMP reference is not possible for me, unless you know where it is available online? I have a few countermarks on central Indian coins, but little idea what most of them represent, or who struck them. You may remember that I sent you scans of three of the latest additions, none of which meant anything to you, either! So what chance do most of the rest of us stand of 'breaking the code'? One day, when all other projects have been finished.......
