［Business Writing] Find problems in following writing

Please try to point out problems in following internal corporate communication. If you want, you can rewrite it.

Please find attached a copy of a news release entitled "ABC Plastic To Feature its Extrusion and Injection Molding Products at the NPE and ANTEC Shows." This news release highlights the output extruder screw, and it is my understanding that this extruder screw is no longer a viable end product and should no longer be promoted. This release, to date, has generated three letter inquiries to the Kansas City office and, if indeed we no longer offer this product, will cause difficulties with potential customers. Will you please advise me at your earliest convenience of the correct status of this product?

Sincerely,

Pat Jones, advertising manager
