have to say that i have seen the gazelle and the dynamarks before on old sales leaflets etc and had not picked up on the fact that they do indeed have some very similar features
Found this handy little tip on how to build a cheap baking soda air blaster for cleaning carbs or other small objects etc

Thanks Meadowfield (Mark)!
Thank you Matt! Yes, I don't think Westwoods were ever sold in the USA, but interestingly the older ones like mine look a lot like the 1970s Dynamarks.
