With regard to reintroduction of Eastfield Models chassis kits, there were notices on the front of the Burntisland stand at Glasgow saying that this was happening. Â
Unfortunately I can't remember the name under which they would be sold.  The J83 was already out and available on the Parkside stand, at, I think, £28.  Somewhat more than Eastfield Models chassis kits were going for on Ebay earlier this year, if I remember correctly.
