Well I think I will call it finish, heaven knows I can sure go on and on and on by adding more to her. I made a Youtube video with a short montage of progress pics. Been playing with the Windows movie maker program.
I added a hand grip to the gunner's rotating MG window. 
Grip handles and a side mirror to the pilot fwd window. 
I did clean up the inside frame work.
For the gunner belt, I went ahead and used the kit part and modified it by sanding of the outer belt ends, cut out holes in the 2 buckles than used the remaining pieces from the RB seatbelt set to make the buckle ends. 
Figuring that the belt would hang lose when not in use I attached it to just one side letting it hang down. 
Some of the adding plumbing I put into the engine area.
If this were a 48th scale kit I would never attempt to do it but in this scale it begs for more. 
Of course this being an AIRFIX kit, the engine cowling panels don't want to fit right. I fiddled with the top cowling to look like it's flush with the middle panel while on the other side there's an unsightly gap. 
I also noticed that I got the antenna wire a tad too tight. Wrote it up for maintenance to fix.
You can see how it gaps at the front just above the spinner. 
Looks almost ready for take off here. 
I was dusting it with real sand for a slightly weathered look. 
The sand color looks darker when photographed inside. 
Bish...let me play around with the camera again in the morning to see if I can get better light for a final pic for you to post with your others unless you like one of the above photos?
