Following more research into the two Bandel patterns, I have felt it best to reverse the numbering of these. The reason being, is that the -2 pattern is actually much earlier. The following now applies:
Now Bandel-1 from c.1962, predominantly 7-inch in size
 | | Now Bandel-2 from c.1969, predominantly 4-inch in size
 |
The necessary change has been made to the web site as well.
