| Dear Mr Buthly, I am still pressing for hardened shafts as standard for longitudinal wheel housings on dahomey axles because of the ten starting effort & wear. I understand we are to make a new design of Crab for 2 tons & under & this will be a model for enclosed gears. Should this be delayed we at once go on with one of the most used. (5tm) new model Crab, pressed for minimum dimensions with enclosed gears. | ||
