Mr. Goerner Sales manager Mr. Hainz Development engineer Mr. Metz of the Headquarter group - strongly against selling any steel rings after the new plastic rings became available -The result would affect the sale of machines - plastic ring would completely destroy demand for the steel ring - sell the plastic ring only in Bruggeman's market area - continue supplying the steel ring until stocks were used up - no problem with GMD getting ready to produce plastic rings, although he was sceptical of the market acceptance of such a product - expect to recover the investment in steel inventory
