... During a trip to England back in 1972 I bought these two toy XJ-6s and the grey primer one is a modified one from the toy base. Still not happy with the wheel well lips. I work on them periodically but haven't touched the grey one for a long while. The red one I'm keeping untouched for comparison.
Speaking of 420s, I once saw a toy of one online... It was fairly accurate but could never get my hands on one.
