Firefly VT413 access hatch

I also acquired an access hatch.

The rim is marked with an F8 inspectors stamp ; part number J52A6001;

The hatch is stencilled VT413 and the outward face painted Sky and has part number J52A6041 750

The image here on the forum is of this aircraft in red and yellow drone colours – not sky- so hatch removed earlier ?
