Not only to represent the manufacturer, but the hobby as a whole. If you say air rifle to the common individual, they instantly think of some 1400fps gamo, not realising there is a lot more to be offered. Thanks for the heads up!!
Why not contact them and ask for licensing to sell them yourself? Best not to infringe on copyrights and such so getting their permission to use their name and product would be wise before making a bunch of product.
