Thanks Paul....
..... they are what I call "type B"
There seemed to have been another model, which I believe was earlier in the production run, that I refer to as "type A"...... which is about 5/16 deeper and the large bottom screw cap was held by a long cotter pin..... it allowed for the cap to be screwed in to take up wear.
