Hi all eBayers,
I have been advised that the RFM listed is not a Series D, but a series C, which is apparently evidenced by the seat brackets.
Unfortunately the description of this listing in can't be modified (an ebay thing), so the only option is to add the revised description note to the listing.Apologies to the bidders to date, but this should not be too inconvenient, as there only a couple of bids to $70, which is well under my reserve price.
