vhawk, (I feel like I am addressing a Navy pilot on the net?)
I wish you had joined earlier and posted your M42 officer. I was in TO last week, I would have pestered you to visit and see it. My personal "Holy Grail" is an issued M42. I see yours has the 1857 75mm Stamped metal Kokarde with silver affixed ring which is what is normally found on surviving examples. The 1842 75mm leather Kokarde w/ silver metal ring and the 1846 75mm silk Kokarde with silver painted ring just did not last well enough. There are other issues as you mentioned with the one on ebay, my concern was that the rear spine did not fit the shell at the bottom and I am reasonably sure the Wappen is actually the M42 converetd to M1860 when the Bandeau was added. With that Bandeau missing it leaves convenient holes to affix the Wappen to a shell like the the original 1842 until it was replaced by screw posts in 1843 etc. Again, thanks for posting your M42 officer, not too many of those in collections.
