I had a Crossle 32F; great cars!!
Have you considered converting it to a 33F and racing it in the Historic FF2000 Championship?

At Race Retro I noticed the top 1600 cars being sold for £9,000-ish; average FF2000 are worth £14k +; might be a way of increasing the value of you car, while you're restoring it it
