Mr. Eisenberg.

What about the widths of the lands and grooves? Did you measure those?

Mr. Cunningham.

Yes; they were also the same. In other words, when I say it has similar rifling characteristics--the widths of the lands and the grooves is taken into account the rifling characteristics. It has the same width and number of lands and grooves and a right twist.

Mr. Eisenberg.

Now, how many other--well, before I ask that, you have also established that the bullets were .38 Specials?

Mr. Cunningham.

That is correct.

Mr. Eisenberg.

And the manufacturer of each bullet?

Mr. Cunningham.

That is correct.

Mr. Eisenberg.

Would you say they had been fired therefore from a gun chambered for a .38 Special?

Mr. Cunningham.

Yes; there was no indication that they were fired in a weapon other than .38 caliber.

Mr. Eisenberg.

So that the weapon was a .38 Special weapon with five lands, five grooves, right twist, and with the same dimensions for each land and each groove.

Mr. Cunningham.

Yes, sir.

Mr. Eisenberg.

Now, would the entire production run of this model conform to that description?

Mr. Cunningham.

Yes. And also there are other models.

Mr. Eisenberg.

Other models also produced by Smith and Wesson?

Mr. Cunningham.

Yes; in .38 Special.

Mr. Eisenberg.

Could you estimate the number of those guns?

Mr. Cunningham.

May I have the NRA reprint? My estimate comes from the figures that are set forth in Commission Exhibit 593, which states that by 1942 there were a million "Military and Police" revolvers, which is the prior model to the Victory model, which they produced.

Representative Boggs.

That is this model?

Mr. Cunningham.

No sir. But the model has similar rifling characteristics.
You could not distinguish between them. In other words, one is a commercially made gun--this is strictly a wartime gun. Also production of the "S" series continued until 1948, when the "C" series was started, including over one million "M&P" models, including the Victory model, which was this model, were manufactured between 1942 through March of 1948; and since that date, Smith and Wesson has produced over 500,000 "M&P" revolvers in the "C" series, which, when you add them up--there are over two and a half million.

Mr. Eisenberg.

Two and a half million?

Mr. Cunningham.

Over 2 1/2 million.

Mr. Eisenberg.

Now, apart from specially handmade or equivalent weapons, how many other types of weapons have you encountered which have these rifling characteristics?

Mr. Cunningham.

Other than possibly a Spanish-made copy of the Smith--the Smith is the only one in .38 Special now that will have similar rifling characteristics.

Mr. Eisenberg.

Now, when you say Spanish-made, you are referring to the basement type of operation?

Mr. Cunningham.

Yes.

Mr. Eisenberg.

Now, this weapon did not produce, and does not produce--that is, the weapon 143--does not produce identical microscopic characteristics from bullet to bullet, you have testified. And you have told us that the reason might be that the weapon was rechambered but not rebarrelled, so that the .38 Special is slightly undersized for the barrel?

Mr. Cunningham.

It has not been rebarrelled.

Mr. Eisenberg.

That's right. So when you fire a .38 Special, it is slightly undersized, and this might affect the barrel characteristics? Wasn't that your testimony? That the .38 Special is slightly undersized?

Mr. Cunningham.

Yes; approximately four-thousandths of an inch.

Mr. Eisenberg.

Now, could you therefore limit the number of possible weapons from which the bullets might have been fired, not only to the 2 1/2 million
