New updated adapter plate for Manfrotto 405/410 gear heads
They do include bubble levels now, and with my F63 series clamp thank to small cut out in the clamp original level is also better visible.
I do have Revision 0 (rev0) plates
and Revision 1 (Rev1) plates.
Update as of Dec 2011
After few months since change was introduced looks like all 405 gear heads are equipped with REV 1 mounting pattern and Junior head 410 is equipped with REV 0 mounting pattern.. This info was confirm by Manfrotto help desk in Italy but I didn't receive confirmation that all of them are made that way. Just in case I would sagest to purchase gear head before placing order for adapter plate.
