Mr. KELLERMAN. There are no running boards. Mr. SPECTER. Is there any place on the car where someone can stand up and ride as it proceeds in motion? Mr. KELLERMAN. Yes; on the rear of the vehicle, sir. Mr. SPECTER. How many such positions are there? Mr. KELLERMAN. There is a step on each side of the spare tire, one man on each one. Mr. SPECTER. And is there any facility for holding on with a man riding in those positions? Mr. KELLERMAN. Yes, sir; there is a metal arm erected on the trunk where a man can hold on while standing on the rear of the car. Mr. SPECTER. All right. May it please the Commission, I move that Exhibit 346 be introduced in evidence. Representative FORD. It will be so admitted. (The photograph referred to was marked Commission Exhibit No. 346 for identification and received in evidence.) Mr. SPECTER. With reference to the bubble top which you have heretofore described, of what is that composed? Mr. KELLERMAN. It is composed of plastic, clear plastic substance. Its use would be for a weather matter whereby the President or his occupants can see out. It is not an enclosed car. Mr. SPECTER. Is it bulletproof? Mr. KELLERMAN. It is not bulletproof. Mr. SPECTER. Is it bullet resistant in any way? Mr. KELLERMAN. It's not bullet resistant. Mr. SPECTER. Could you describe in a general way at this point what efforts, if any, have been made to obtain a bulletproof clear top for the President's automobile? Mr. KELLERMAN. Presently? Mr. SPECTER. Presently or heretofore. Mr. KELLERMAN. I am going to have to go in the present day. Mr. SPECTER. Fine. Mr. KELLERMAN. This same vehicle, I understand, is being completed with a bullet-resistant top and sides. Representative FORD. Can you explain the difference between bullet resistant and the existing kind of the top? Mr. KELLERMAN. I can't; I really can't. I have been behind on this thing and I am at a loss for a better answer. Representative FORD. Could the present top deflect in any way, destroy the accuracy of a shot? Mr. KELLERMAN. This would be a guess, Mr. Congressman. I would think that it would be deterred for, let's say, the velocity of a missile coming in at great speed, I think it would deter it; I don't think it would eliminate--it still would enter the top. Representative FORD. The vehicle. Mr. KELLERMAN. I am sure; yes, sir. Representative FORD. But as far as you know the top that was available would not impede the projectile? Do you know whether or not it would deflect its accuracy? Mr. KELLERMAN. Well, I have tried to study that, sir. The angle of the back as an example which is, what degree I don't recall, hoping that--of course, it was now known to be an upshot into the vehicle hoping that it would deter its force and so forth, but I really don't know. I kind of doubt it.
