There are differences. In the original M49 there are three brass standoffs on the hi-z board that connects the hi-z section with the capsule cables on top of the plastic cup. The standoffs also holds the plastic cup in place.
There are no such standoffs on Poctops PCB. The cables from the hi-z section have to run all the way from the hi-z board to the capsule (as I understand it). That is not very practical. You will probably have to splice the capsule cables somewhere along the way.
Dust and moisture protection is good, and was used in both the M49 and the ELA M-microphones. But you have to remember that these mics where used for everything back in the day. Even outside, on location. You don't see that kind of encapsulation in modern microphones (and they are even more "hi-z" then the old ones).
As for isolation: Air is a very good isolator. The only better isolator is vacuum.
