8In any case where this Part applies, section 272(2) shall have effect as if the following proviso were inserted at the end—
“Provided that where capital gains tax is chargeable, or an allowable loss accrues, in consequence of a death before 31st March 1973 and the market value of any property on the date of death taken into account for the purposes of that tax or loss has been depreciated by reason of the death, the estimate of the market value shall take that depreciation into account.”
