Thanks sailor! I was very pleased when it came today & turned out to be as nice as it is for $75
Now, of course a new thing like this generates new questions. I haven't seen the protective fuse cover in photos or drawings of these. Please tell me that's super rare!

Another thing is on the base. There is some remaining adhesive over the primer area. Of course my first thought is that is was from a price tag & I was thinking of removing it. Thing is, I have a 'like new' T-89 knee mortar round & it has the remaims of a paper cover over the bottom of the base, so??? Whatcha think? The adhesive looks pretty old.
I tried to edit photos in the original post - can you do that? Anyway, here's some more.
