I just remember seeing it in another thread and there are two spellings for saber for a fencing foil but not sure about the 13th. I just had a look but couldn't find it!
For Captain2. Thanks for your help. The "r" comes from my answer to 2d ie pewter. Q. Sn+Cu will make an alloy for you (6). I have the same doubt about sabre, I just can't parse it.
