Above Google image, July 2017. This to be the spot of the former pub.

Further information received from Alan Mason says the following:- "The place changed radically in the late 50's early 60s. Basically, John Penn Street used to be part of Coldbath Street (formerly Bath Street) - hence a degree of confusion as to where stuff is. The pub was located on the corner of Bennet Street; this road was severely truncated in the early 1960s and what remains is now Bennett Grove. At the end of Bennett Grove is a collection of garages and it is the John Penn Street entrance to these where the pub used to stand. Hope this helps.

From the Borough of Greenwich Free Press, 29 March, 1862.

William Butler, landlord of the "Ironfounder's Arms," Bridge Street, Greenwich, fined 5s. for being drunk. (Is Bridge Street related to this area? Local knowledge needed thanks.)
