Using Enums for property customization

I'm making a shooter were the player will have different weapons and stats based on the current equipment it's wearing but I'm having a hard time figuring out how to do this as I haven't used Enums before.

Below I have three different scripts, the Player, the PlayerProperties, and the StandardArm. I want the Player script to be able to take the speed values from the StandardArm Script and add it to the current speeds using the PlayerProperties as the middle man. The problem is I'm not sure what I need to add in for this to work.

//First Script

 using UnityEngine;
 using System.Collections;
 
 public class Player : MonoBehaviour {
     
     private float     horizontalSpeed = 10.0f;
     private float     riseSpeed = 10.0F;
     private float     dropSpeed = 10.0F;
 
     private float forwardAddShootingSpeed ;
     private float backAddShootingSpeed ;
     private float riseAddShootingSpeed ;
     private float dropAddShootingSpeed ;
         
     void Update (){
 }
 }

//Second Script

 using UnityEngine;
 using System.Collections;

 enter code herepublic class PlayerProperties : MonoBehaviour {
     
 
     enum Weapon {
         Standard    = 0,
         SprayGun    = 1,
     }
 (int)PlayerState.AirFighter;
     public int     armWeapon = (int)Weapon.Standard;
     
         
     void CustomizeAirFighter () {
         
         switch (armWeapon)
         {
         case (int)Weapon.Standard : 
             print ("Standard Shooting System");
             break;
         case (int)Weapon.SprayGun : 
             print ("Spray Gun System");
             break;    
         }
     }
     
 }

//Third Script

 using UnityEngine;
 using System.Collections;
 
 public class StandardArm : MonoBehaviour {
     
     private float forwardShootingSpeed = -7.0F;
     private float backShootingSpeed = -4.0F;
     private float riseShootingSpeed = -4.0F;
     private float dropShootingSpeed = -3.0F;
 }

I left out the bulk of the code not necessary to my problem so I hope it's not hard to understand. I basically just want to know how the speed values from Standard Arm Script get fed in to the PlayerProperties script witch then feeds in the currently selected enum value to the player script. I'm using C# but any help would be most appreciated. Thanks.
