Argyll Group - Safeway - Morrisons capital gains

GazHol

I’m helping a relative with some capital gains and they haven’t been 100% diligent in keeping their paperwork. All I can find is 1,500 Argyll Group shares purchased and 4,004 Morrisons currently owned. Is there a way that the takeover of Safeway and then by Morrisons could have turned 1,500 shares into 4,004 without any other purchases? Or were there rights issues which if taken up would have increased a holding from 1,500 to 4,004?

03-Apr-1987 Argyll Group 1,500 shares purchased at £4.08 with £147.72 costs

Mar-2004 for each Safeway Share 1 new Morrisons Share plus 60 pence in cash. Each Safeway share holds 40% of the enlarged Morrisons.

Jul-2009 4,004 Morrisons shares held

If the number of shares had stayed the same, then the £4.08 would have turned into 60p plus 40% of £1.87 in 32 years. (The loss is not a problem as there are plenty of gains elsewhere as we try to get as much as possible into a S&S ISA).

Any help or guidance would be most welcome, the Morrisons Investor Relations web site has very little information about the capital gains impact of the takeover.
