It's Nov 2005 and surprisingly unworn. The rear rim still has the original fine grooves, the insides of the T3 hub are great and it probably had its original tyres. Just a bit of surface rust on the hub and seatpost, which scrubbed off easily with oxalic acid paste. The paint is really good (there's a hard black undercoat to the silver parts); my 2009 S3L had to get it resprayed after a year because it all started flaking off. At the time, frames were being blasted in London and shipped to Wales for powdercoating a few days later, which meant some developed surface rust and the powdercoat didn't stick well. I believe they do it all on one site now.
The rear hinge had some play, certainly up to the 2mm allowed. Given the lack of wear elsewhere, it could have been over-reamed at the factory, or 16 years of sitting around did something adverse to the nylon facing. I have the new bushes in and someone is lending me the proper Brompton reamer. I could have a go with a 3/8" hand reamer but it would probably end in another bush replacement! The proper tool is a taper reamer with a very long pilot, which keeps it parallel and allows a "shave a little, then try it" approach to get the best fit.
