Roger, thank you for your reply. I'm hoping for a real close color match, but I'm anticipating repainting the B unit as well if it's not. Not only is there the age issue, but paints do vary from batch to batch; method of application and the shooter; and, other factors influence the "final" color. For myself, I don't have that good a color eye, and no chance of mixing paints to achieve a good match.
LOS, thanks for your reply. I emailed you for some additional information.
Thanks, again, for the replies.
Merry Christmas
