Thanks Bob & Daniel.

Daniel - does the #513 have the collar and more detailed windows?

You'll recall that when production was shifted to Canada, Castle Sudios first cast some pieces from the California molds, then modified them with the more detailed windows and the ventilator ball 'collars'.

What we're moving towards here is being able to pinpoint more closely when production was shifted from Canada to Malaysia -- somewhere between #149 and #1648. If JJ and Sean check in we can narrow that down more closely.

My Canadian #1107 has the collar.
