Thank you for the offer but I no longer need the 3D set.
I purchased two of Blue Ridge's sets before they ran out of stock. I was going to use 3D's set on California but JSP's searchlight platform wouldn't compliment it, so will use the B R sets on California and Trumpeter Maryland, and the 3D foremast alone will take care of my HP '45 Colorado.
Then apart from Idaho, all my US big five versions have tripods.
Thank heavens for 3d printing. Photo etch had a go over the unsatisfactory solid resin but is unable to capture the distinctive and very important parabolic curve. Makes all the difference.
Thanks very much anyway for offering help, a very Steel Navy thing and much appreciated.
