Hint
Which letters are missing?

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.
