The Union Arm is an elusive little canal, a twisting arm which came off the original Birmingham Canal near what became Pudding Green Junction.
Its course was complicated when the New Main Line was built in the 1840's, cutting across its line with both its start and terminus on the eastern side but the meat of the waterway on the west.
The little network of canals and basins are long gone, but I recently found a photograph in the Hugh Potter collection taken in the early 1970's which shows the entrance the the end basin, and the factory backdrop still exists providing an accurate location.
If I find any more images of the Union Arm I will add them to the post.

Duncan Moore did some more research on this elusive waterway and found a set of aerial shots which capture much of this Branch:

There is a risk of disappearing down ever smaller rabbit holes when it comes to tracking down the lost sections of the BCN. So, rather that create a new post and given its proximity to the Union Branch, let's include the Izon Old Turn here.
Just as the Union Branch ended up straddling the New Main Line canal, the construction of the New Main Line also created a loop canal which used to be part of Brindley's original Birmingham Canal as it curved inti what became the Wednesbury Old Canal at Pudding Junction. Not that there were any junctions here in Brindley's day!
