Those symbols are from SPI, the plastics industry trade association (North America). Vintage Ale bottles are from Italy and from long before we had those symbols. All my Ale bottles say is "GUARANTEED ODOURLESS AND TASTELESS". No doubt today someone will say they cause cancer.
I have a red one and a yellow one; they came in various colours. If you want to repair a cracked one, try "welding" it using a similar unsalvageable bottle and a soldering iron. However, I doubt if the repair will stand up to squeezing.
