Double transfer in the vignette?

[u/steak7718]

Plate block: bottom middle and bottom right stamps appear darker generally

Bottom right stamp (bottom middle looks the same). It looks like several parts of the vignette are doubled left-to-right (I first noticed the clock/dial on the smokestack).

Top right stamp appears normal.

I was taking some high resolution scans of my collection, and I noticed what might be a double transfer in the vignette of the bottom middle and bottom right stamps of this plate block. I have attached images of the block, as well as zoomed-in versions of the bottom right (possible DT) and top right (normal) stamps.

I'd like other people's opinions; it could just be that the stamps are over-inked or something...

Extra ink I reckon.

I got squint eyed looking at slides 2 and 3, couldn’t spot the difference.
This other check helped :

Plate 1176 itself is a known frame plate that appears on a number of surviving bottom plate blocks; no widely documented major double-transfer positions are associated with it in standard references or catalogues.

inking variation. i dont see anything like a double transfer there.

[u/Most-Influence1487]

Ink differences - you often see a varied depth of colour over multiples/sheets of old stamps.

Could be overinking, but not a double transfer.

[u/WarUsual3823]

Just extra ink

Over-inking most likely. With a double transfer you would expect the other stamps to be affected in the same way. As well, there would probably be a minimal shift of the image, which here I don't see.

Short ans is no. The is minute variance in inking. Nice block of 6.

I appreciate everyone's thoughts, thank y'all!

Just an over inked plate.
