Well, the tbm file you included did have it flagged as a bomber, so I assumed that you would want it as such. Besides, as this is a Public release, it wouldn't be all that surprising if someone wanted it as a player-flyable ship, so having one with primary & secondary firepoints already set up seemed to me to be a good idea. The unshielded one I included doesn't have the banks added, so if you want a shield for that one you can just import from the shielded one.
On the question of shields, the included mesh is... simple, to put it gently. It appears to me that you used MODview's auto-shield function to create it. Most fighters and bombers are made with a shield mesh that follows the contours of the ship mostly, so by that standard it is quite poor, unfortunately. That said, some modelers don't do shields very well, so I'm not complaining, and I'm no modeler. Furthermore, while MODview and PCS2 display the shield mesh in a proper position, the FS2 Lab shows the lower tip of the nose protruding from the front end, so there may be a miss-alignment between what the POF editor programs display, and how FSO renders it.
Also, I forgot to mention that I set up rotation axises for the multi-part turrets, but there appears to be some miss-interpretation between MODview and PCS2, which have different interpretations as to which axises are which. You may want to take a look at this when doing the uvec fvec. I also changed the table to give a AAA for the chin turret.
