Thanks for your question and asking for me
No you need to establish the full value position - so either this equipment has been subject to annual investment allowance - (so 100% relief claimed on its value in the year of acquisition) OR capital allowances were applied (such as in a general pool)
But you need to know
1) What the purchase price was
2) How much capital allowances are claimed
3) To establish the value still to carried forward from the last full tax year end
4) To see whether you have a further capital allowance to claim or a balancing charge to add back into the profits.
