So I went to my stash, where I have only a "re-bagged" version, in a generic box with color copy-of-a-color copy-of-the original, pasted on the outside. It looked like absolute sh** - as I'm sure you can imagine - however I realized I could "merge" the colors (such as they were) with the contrast of a very good black-and-white copy. Which I duly found displayed prominently on the first page of the instructions (particularly typical of early Revells and Auroras).
Without boring you with how I did it (in Photoshop® - and yes, it is minor proof of genius ) you can see for yourself the results - plus, I included the b&w-only version, for your interest.
So - you're welcome, buddy! And be sure to send me your newest Boston pics, and writeup(s), when ready, Mikey.
