nf '76.

Times have changed a lot since the men back in 76 took their flintlock rifles out to make sure they-and you here in 1955-could be free citizens. Yep-times have changed, but one mighty important thing they did, and you still do, is the same today as it was in 1776. In fact, it's a bigger job now. That's maintaining your equipment. Where the men of '76 had rifles and muzzle-loading cannon for weapons, and wagons for transportation, you have the best that can be produced of slick-operating weapons, tanks, trucks-you could add lots of things to the list. And that's where the iob gets bigger-maintaining all this equipment so's it'll operate and keep operating when the tine is drawn and the chips are down. That's where you come in-to keep your rifle, Jeep, tank, gun or whatever you've got in tip-top shape. You do it with lubing, cleaning and the best of babying care and operating. With the right kind of maintenance you and your equipment'li be ready to carryon the tradition of '76.

Besides hitching the tow-bar to the towed vehicle's front-axle, you've got to rely on the lifting hooks co take tcr off noching by this trick of completely lu- the ground. You can do this by clampbricating the power train. That way the ing a wire rope across the hooks, and 47

official

When you've got a complainc about your equipment-it's not made right,Jt doesn't work ,right, or it breaks downmake it official-like it says in SR 70045 ·5. Send in a Form 468 (UERUnsatisfactory Equipment Report) to the Chief of Ordnance for Ordnance eq uipment, and to the Chief of Engineers for Engineer equipment, both at Washington 25, D. C. They're mighty anxious to find out what's wrong with their equipment so's it can be fixed up right quick.

Always turn off the switches on your T46El range.finder when you remove or replace a lamp. Else you'll burn out the resistors. Make up a decal with somcthing like: "Warning-turn off rangefinder switches before removing lamp" and placc it so you'll see it. The new range.finders already have 'em. An MWO is also on its way to take care of the situation.

flexible?

The flexible drive shaft on your M38 (T154) computing sight in your selfpropelled twin 40·mmM42, may be getting a little stiff in the joints. So dob a speck of grease on the retaining rings at each end coupling. But don't lubricate the shaft. It's already taken care of.

Man - when you tell about the pass experiences you had last night, you don't spare the details, do you? PS doesn't want you to spare them, either-especially when you write in about a piece of equipment. By giving the complete calling name of all parts and pieces of major items, you can help Sgl Half·Mast and Sgl Dozer find the answer to your problem in a hurry. Just address it to Sgt Half·Mast or Sgt Dozer in care of PS Magazine, Raritan Arsenal, Metuchen, N. J.
