It is not one of the ones in the Koster set. I have been thinking about making one but I have found no drawings and no head on view. We can probably come pretty close with the photos I have posted here. Hell, who can prove us wrong ! It appears to have the standard K4 mount on four posts albeit different from either the round one on "Miss Ouachita" or the later metal one. And of course totally different fro what we see in the Belle. I refer to this one as the recessed mount. Looks to me like they formed a recess and then cut out the nose for it. I think I have seen a more head on view so I will do some more looking. The best approach may be vacuforming the recess separately and a new nose, then cutting it out. Dunno, but will be worth investigating as I know you want it right !
Thank you so much. I had a feeling about this and scratch building. Sigh.
BTW, another question. Is Vicious Virgin's nose configuration the same as Luscious Lady's? (There's a reason I ask).
