Miranda threads are a lot coarser than what's on a T mount. What we generically refer to as a T mount, is more specifically known as a T2 mount and didn't come about until 1962. There are earlier "T mounts" which are slightly different. (edit: or so I thought - apparently the only difference between the T mount and the T2 mount is the T2 has set screws in it so you can orient the lens properly in the mount. But some lens manufacturers had proprietary mounts using the same principle)
