Forks on many guns are threaded and glued, which means they they are more liable to develop leaks over time than brazed tubes.
But it also means they can be removed and resealed, but that means you end up seeing how little care the manufacturer took in one of the most critical areas of a spring gun. No matter how well they polish and blue the finish, it really does not mean a thing if the fork threads run into the compression chamber...
And yes, the Meteors are mine, I just can't help myself when they turn up cheap
A couple Meteors have been sold, and a few bought since that picture was taken, so there may be one or two more now
