I don't mean to pour cold water on things but I have a problem with my Kestrel, which I collected today. When I took it out of the box at home to test it, I found the buffer beam at one end had snapped off and was hanging by the ETH cable. Also very minor damage to the body end. I rang the shop, which will not be named, and the proprietor informed me that a few others in their consignment also had broken buffer beams, all at one end only. Most were OK though.
By the way, 1N06 was an East Coast 'high-speed' set of air-braked stock, formed 3 TSO IIa, RB, RU, 2 FO, BFK IIa. RU and Mark IIa stock from Bachmann. RB from Mainline. FO from Replica.
