"RY" suggests Railway. The only line I know of with the reporting mark S M S RY is a long way off... the Madras & Southern Maratha Railway in India. However, I note that you have posted other Indian railway tokens, so that would seem to be a plausible guess in this instance.
PK & John, many thanks for the info, I just did not search far enough. Seeing that I just purchased over 100 lbs of middle east coins, thats over 10,000 coins and these 5 single canteen ones were the only ones in the batch. I shudda figured them out. I sure appreciate your efforts. Pocket Change.
