I recently saw that a set of early type keys were on ebay. I have the early two key system although my door key is missing the electrics, outershell and button. So I jumped at the opportunity to buy the parts.
The seller (Ria) contacted me and told me she had some other things for sale. Her late husband worked at DMC Irvine California and she still had some of his old work stuff. I bought a shirt with the DMC Logo and his name badge (coincidentally Kevin). Also Ria sent me a photo of her Kevin delivering a Delorean to Johnny Carson's house and some business cards.
This is a pic of Kevin and Johnny Carson wearing surprisingly tight-fitting shorts/ hot pants/ y fronts .....
