"Bonhams are offering at auction on 29th April 2013 a 4½, chassis number FB3324. Having inspected the car and the history file there seems to be some confusion with that and the listings on your excellent website. The chassis was replaced by Bentley in 1929 under warranty which explains why it is a heavy frame and has 4 rivet fitted dumb irons. It is listed as having the chassis frame of XF3513, but in fact it has the engine XF3513. The engine number quoted SR 1407 (a 3-litre) was indeed in the car when purchased by the owner (in 1960), but this was removed and replaced with XF3513 during restoration by Ian Lock in 1976.

The chassis is correctly stamped FB3324 on the NSF dumb iron and on the NS cross member. I do trust you will be able to update your records accordingly."
