I think the bogie came with a big job lot of parts I got on ebay from Cost Rica about 10 years ago because of the unusal location there were not many bids and got the lot cheap even if the postage was expensive. I would of liked to have seen the face of the of customs officer who prcessed it into the country as it was a tatty old fruit box covered in stamps, lumpy, rattling and quite heavy, I bet the X-ray scan was unique as there were lots of wheels, old circuit boards together with tools, whole and broken wagons and loco parts!
