MP E7's

I would like to do a pair of MoPac E7’s however they have paired porthole windows rather than the standard square ones. I was wondering if anyone makes something to be cut in to replace the square windows with the round portholes.

Thanks.

I have pictures of the prototypes. Neat looking unit.

You may have to do an internet search, but there is a Missouri Pacific modelers group society with a website that might be able to help you.

Thanks for your help guys.
