Mr. Liebeler. You have testified that Oswald told you that he had received some training in the use of photographic equipment when he was in the Soviet Union. Did he mention any other training that he received in the Soviet Union?
Mr. Ballen. No; I think I discussed a little detail with him about photography, continuous cameras and things like that, and he stated that he could operate most of the machinery we had down at Ross Avenue.
Mr. Liebeler. Did he indicate to you a general comprehension and understanding of that type of machinery?
Mr. Ballen. I am not that familiar technically with the equipment myself to have gone into any explicit detail, but I mentioned different types of machinery, the M-4, blueprint machines, Repco continuous cameras, and he said yes, he could operate all those machines.
Mr. Liebeler. Did you have any discussion concerning his wife, Marina?
Mr. Ballen. No.
Mr. Liebeler. Did you ever meet Marina?
Mr. Ballen. No.
Mr. Liebeler. Do you speak Russian?
Mr. Ballen. No.
