I have been thinking about repro socket and tommy bar for a while since I have an original car with complete tool kit. They are ideal candidates for 3-D printing; you either need a surfaced model or a scan of the actual part. To that end I have made drawings of the parts since my search of the Rootes Banbury archives did not turn up a copy. I did find the Rootes drawing for the tool bag however. I took the car to Tiger 50 in the UK this year so have been busy with that and a new house. If anyone has access to a 3-D system PM me.
I would imagine that Britool will/would have the drawings.
May be worth an e-mail. Who knows.
