This B-17G had staggered cheek guns,No Cheyenne tail turret these were fitted from 55-VE onwards. It would have only carried national insignia,squadron codes would have been applied at it’s operational base. Staggered waist position. Aircraft in silver finish.

I don’t recall B-17s being fitted with staggered K-5 waist-guns. Think these K-5’s were always “unstaggered”. Not 100% sure without my references in front of me.
Also, it is quite possibly this ship would have had a Cheyenne tail turret fitted in Cheyenne, Wyoming en-route to the UK after leaving the factory. I say this, as I know that B-17G 4-297286 (Boeing Block 45) left the factory with no waist guns, a “stinger” tail turret and no cheek guns. She arrived in the UK with a Cheyenne turret, staggered cheek guns and “unstaggered” K-5 waist guns after two stops, one in Wyoming and another at a modification centre whose name and location escape me for now.
I would propose that this same set-up would apply to the one referred to here given the close proximity to the production numbers. However, as “my” B17 was delivered in Jan/Feb compared to this one in June in might be that the waist positions ARE staggered. As I say though, I don’t ever recall seeing the K-5s being staagered.
