Answer
The letter was written on a typewriter which has a problem with the middle row of letters, which print spaces instead. The letter should have read:
Dear Sir,
I recently visited one of your outlets to buy one of your typewriters. However, as you can see I am having a small problem.
The middle row of the keyboard appears to be faulty.
I would be very grateful if you could despatch a replacement by return post. Failing this, could you please send an engineer to resolve this problem as a matter of urgency.
Yours faithfully,
Mrs Middins.
