P40 VP Mod Question

[NO.20_Krispy_Duck]

Here's weird issue - I have VP Mod. I noticed that I somehow lost the rear external iron sight on the P-40E. I see only the front one, not the rear one which is the lollipop shaped sight on the hood. I don't use it, but it's nice to have just for completeness of the appearance from the cockpit. Externally I still have both of the iron sights, but internally the rear lollipop sight is not visible. Any idea how I add it back in?
