If memory serves me right, they were probably oval in shape and not the 4 finger grip with ribs along the top.  They were made originally by John Bull, later acquired by Dunlop.  Extremely difficult to fin and most have perished.  I have seen some that have turned a horrible orange colour.  I did hear that there was a guy/trader at Stafford motor cycle shows who did spares for motor cycles, he may have some copies.  Internet search I am afraid.
