it does not look like the standard Lucas ACR 17, possibly an "uprated upgrade", see for example http://www.ratsport.com/PBSCProduct.asp?ItmID=9667761 (no endorsement or affiliation on my side)

It looks like a Bosch example as fitted to VW & Audi in the late 1980's and 1990s.
Unlike Lucas they were well built and reliable.

Looks more like a Bosch than a Lucas LRA100, I used on on a Zetec conversion and also on a all steel X/flow that literally ate Lucas alternators and starters finding just about every failure mode, much more robust.

Does not look like a Bosch to me, I have an 80's Bosch (from a VW Golf) on my S2 and its nothing like, looks more like a Motorola to me although some Motorola's had a separate regulator.

My vote is Hitachi, e.g., 4.2 Liter Nissan Diesel, 80 Amp. (Close but not same).
