Agreed re the six shooter--except that on my second one,I mounted it on the outside of my hundred-year old wooden flight box,then wiped off the crank handle on the car door frame in no time....
But real modellers have cunning plans....I just persist with leaky free-floating hand pumps until they become so painfully slow that someone can't stand it any longer, and presents me with a new one...
It's worked twice up to now...
