3 Inch RF casing. What gun?

[DEADLINE222]

Picked up what I thought was a typical 3/50 caliber casing.

Cleaned it up to reveal it is a 3 Inch RF casing. It was made at he WNY in August of 1906.

I assume RF is "rapid fire", so exactly what gun does this casing belong to?

Thanks in advance.

I'll stand corrected and remove my post.

I'm a USN KW era Gunners Mate and so RF to me means rapid fire as in the 3"/50 MK 33. Everything before that was slow fire, sometimes painfully so.

Thus, I am aware.

The nomenclature on the casing headstamp is "3IN R.F." .

To better answer your question, I assume RF is rapid fire because a Google search of the aforementioned term yields "rapid fire guns".

There are several variations. The exact one of which is what I seek.

A picture of the headstamp and the cartridge case would help in this situation. Also case length, case head diameter.

The casing is 732mm tall.

The diameter of the casing's head is 135mm.

Seeing an abundance of information pointing my casing to the M1902M1 RF, which seems to have been a mainstay gun for seacoast and harbor defense batteries.

However, it seems that this gun was also utilized on many of the pre-dreadnought, armored cruisers as well.

Could you post a photo of your RF case, perhaps along side a standard 3"/50 cal case?

3 inch rapid fire on the left.

3 inch, 50 caliber on the right.

Obvious differences between the two are found in the total length and the rim.
