Here's a site that has large scale R?C PT Bpoats, with lots of cool pics and vids that might be helpful.

Back in the mid 90s I constructed the Dumas 1/20th scale PT-109, which measured 48in. from stem to stern.
I finished it in solid forest green which I had phoyos from in the old Webster's WWII Encyclopedia. I also had some reseach info I found that stated in the early part of the war smaller vessels usually had a basic finish of dark green or forest green as they called it. Even DDs and DEs were done in that color.
Later in the war, different camo schemes were adopted from what was stated.
Glad to see the MTBs getting an overhaul! Would be neat if the early ELCOs could be seen like MTB Sq. 3 in Manila had.
Is it planned to overhaul the ELCO in SH4 too?
Looking forward to this, even if we only see them in harbors or close to bases.
