Comparison for 1.40 Mitsukaze
First print below is the copy found in Weinbergs book "Kuniyoshi The faithful Samurai" by Hotei publsihing.

B. W. Robinsons book "Kuiyoshi the warrior prints" lists this as S54;40, numbered, censors Hama - Kinugasa
Things to look for:
A. - Compared to Weinberg's above the pattern on the pants is very different in all other prints below, bar R Thom2. Square angled patterns become swirls in a number of places.
B. - The armour reinforcements on the sleeve contain additional rivets in all prints below with the exception of  R Thom2.
C. - The pattern in the armour is more curved in all other pictures, bar R Thom2
D. E. - Some quite obvious differences in the Kanji and furigana Kana.
F. - Positioning of the Kiri seal is different in some prints
G. - There are significant differences in the Kanji characters (sei, chu, gi, shi, den) of the caratouche, noticeable in the other prints compared to Weinbergs and R Thom2. Also notice the position of the censors seals compared to the print title Kanji.

The interesting thing to notice regarding the colours in this print is the colour of the sash, whilst many of the series are seen as brown/tan due to the fading purple colourant, this is one of only a few prints in the series that seems to have an original brown colourant application (Weinberg version). The versions of prints below all have a purple sash and this is then replicated in the pants in most instances. The exceptions being TM which is too hard to tell what colour the pants are, and mine (R Thom), which whilst the sash is actually no where near the bright purple that appears here, the pants don't seem to be the same but faded purple, (analine purples can fade to grey / grey blue) possibly a separate grey has been applied.

The other interesting difference is the application of  a rose or pink around the eyes of  Mitsukaze in some of the prints, (Big, RG, R Thom, unsure in CFA).

Conclusion
Given that all prints here are numbered (a general theory goes that the un-numbered prints are earlier states) we are none the wiser in this regards. However if the pattern in the pants was included within the original keyblock carving, there has clearly been a re-carved block, or part there of. The thing that spells for me that Weinberg's is the earlier version is the rivets within the armour plates on the sleeve would probably have been completed later as they would have been drilled into the block to create an absence of black, (though one could argue that the minute holes could have been plugged). His colours are more reserved and the fact that only 1 of the other 6 other examples is, in appearance of key block lines and  kanji of the caratouch and text, the same!
