Dear Sir, Picture yourself, or one of your men, doing hard labour with an ordinary push pump inflating even one hefty tyre - how exhausting it is! Then see yourself with the HF.{H. W.

Use the enclosed Free Trial Form and get a Belt Driven "Rotoflator" for 14 day's test. Yours faithfully, HARVEY FROST & COMPANY LTD. W E Smith For Sales Management.
