We were very interested in your display at the latest Exhibition held in Moscow. We would be very much obliged if you would send us your illustrated catalogue of your products together with the pricelist, with special reference to all sizes and quantities. We would also like to know what discounts you grant for quantities.
If you can guarantee prompt delivery we would be prepared to place a large order.
We can supply the names of several firms as references.
