I'm pretty certain it's Marquey with a Q but I'll ask Dick. He hasn't returned my call yet - maybe off hydroplane racing - his first love. To my surprise marquey is not in the dictionary (nor with a G) - it's a little furry animal in case you didn't know - Dick lives in the forests near San Francisco.
Never even thought about Toleman chassis numbers. The other TG280 is owned by Paul Flowers of Alabama and looked after by Lee Chapman - see

- about half way down - I'll see what I can do about chassis numbers on those two cars.
