Been working on a breakdown of the modern Astra family from the A50 and Constable to the A100, with about a 350 unit sample size.
Thought I'd share a segment of that information. This information is not complete, only notes external differences, and there are exceptions that do happen, I suspect due to reusing spares, cycling out old inventory, rebuilds etc. I'm not certain if these serial blocks are shared across all of Astra's models, or if they're confined to that specific model. The -95A and -96A blocks are shared across all models I believe
Astra used about five serial number schemes. For the A100, the three relevant schemes are
A####, ####A, and #####-9#A (eg A1234, 1234C, and 12345-95A). (Astra's first schema was discontinued before the A100 was produced, and the last schema seemed to debut in 1997, and I haven't found any A100s still made at that time.)
In the A#### schema, the earliest A100s begins with the R and S block
The W and X blocks are the same as above, except
At this point, the serial schema switches from A#### to ####A, and begins
A block
* * Identical to the W and X block which precedes it
B block
C block
* * Mid to late C block intros block-letter style rollmarks with white infill. This becomes the standard, more or less.
D, E, F blocks
After ####F block, a new serial number debuts, #####-95A. This change is to comply with new Spanish law codifying the serial number schema. This new standard impacts other Spanish gun makers, such as Star. The last digit set indicates the year of production. As such, on Astra, you'll only find -95A, -96A, and -97A, as they went out of business after 1997. The Spanish law required several elements to be included in the serial number; manufacturer number, firearm class, serial number, and year or production (eg 65-04-12345-97A). Astra may have rolled out their new serial number scheme in anticipation of the law change, or, that the Spanish law changed in ' .97 to require these extra elements not present in '95 and '96
#####-95A and -96A

In the A#### schema, the earliest A100s begins with the R and S block
- * Short even slide serrations as found on the A80 and A90
- * Rollmark is generally thin letters
- * Fixed front sight (not dovetailed)
- * Thus far, only found blued examples
- * Grey Box
- * I believe theres a T block that follows this same schema
The W and X blocks are the same as above, except
- * Tall wide slide serrations
- * Thus far, W block is all blued, and X block notes some inox samples
- * Around this time, the mag release button cut out on the grip panel has been chamfered out
- * Green Box debuts, although grey is common also
At this point, the serial schema switches from A#### to ####A, and begins
A block
* * Identical to the W and X block which precedes it
B block
- * Around serial number 0700B, the mag button cut on the left side of the frame is elongated with a cutout extending under the grip panel. Reversible mag release. Not all A100 mags feature a cut on each side of the mag to accommodate this. This feature debuts also on other Astra models such as the A-75L.
- * A sample found with adjustable front sight, and block-letter style rollmarks
- * Last thousand or so B block seems to be inox 40sw
C block
* * Mid to late C block intros block-letter style rollmarks with white infill. This becomes the standard, more or less.
D, E, F blocks
- * Late D block introduces dovetail front sights
- * Block-letter style rollmarks are generally white infilled, but not always
- * Examples with both blue and green boxes
- * Compensated models appear occasionally after this point
After ####F block, a new serial number debuts, #####-95A. This change is to comply with new Spanish law codifying the serial number schema.

#####-95A and -96A
- * Features are identical to the E and F block
- * Inox versions are rollmarked "A-100 INOX", previous serial blocks are not rollmarked inox
- * Inox versions begin to feature Inox controls (take down lever, decocker, slide lock).
- * I have not found an A100 in the -97A block range.
