Not really, Wirth implemented this language more or less after he
quits Working Group 2.1 of IFIP responsible for ALGOL. This ALGOL W
was an implementation of Wirth and Hoare's `A contribution to the
development of ALGOL' (Comm. of ACM no. 6 1966, 413--432) that itself
was based on Wirth's earlier Euler language combined with Hoare's
proposal for records. Wirth and Hoare's proposal was a language that
could become ALGOL 66, that is, it was the language they wanted at
that moment.


In the subcommittee working on a complete proposal for the new ALGOL
(consisting of WIrth, Hoare, van Wijngaarden, and Seegmüller) it was
decided that the new language would be defined in the notation defined
by van Wijngaarden (the vW-grammar). Although it was felt that Wirth
and Hoare's proposal (what would become ALGOL W) was more or less the
right language, it was not defined in the right notation. For some
reason, the language was never defined in the right notation and ALGOL
68 was developed instead.


In September 1966 Wirth reported in the ALGOL Bulletin that he was
implementing this language (that would be known as ALGOL W) on an IBM
360 at Stanford (AB 24, 1966, 13--17). There is one source on ALGOL W
that I know of:
ftp://reports.stanford.edu/pub/cstr/reports/cs/tr/68/89/CS-TR-68-89.pdf
.

Unfortunately I can not really be of any help here than what I have said
already.
