I think these are OLD RL Purple Label -- made by C&J -- from a period just after the Purple Label designation was established by RL, but before RL shifted its shoes to Edward Green. From the early 90s maybe? The "Polo" on the sole is the giveaway IMO.
So if they are C&J, the buy-it-now price makes them about $60 cheaper that the PLAL price for CJ handgrade monkstraps (the Savile) and about $20-30 more than CJ benchgrade (Grosvenor, Malvern, Chalfont). Not a great deal, even at the low-end price of $300.
