Like Nomad I try not to work on radios anymore that I know it will be a real problem to find parts for, That being said I think if you still have the original meter you may be able to find that type meter in another radio and you can remove the face behind the needle and place it another meter I have done this on many occasions and it works great you just need to be careful not to bend the needle in the replacement meter. Hope this helps. On another note I do believe the Super Base used a common meter movement that was used in other radios I just cant' remember for sure Nomad may remember or know if that is true but I'm pretty sure my memory serves me on this and I did this for a customers Super base Oh about 10 years ago.
