So, you have an Icebreaker or Cutter model, and you're thinkin' "How can I get a descent 1/350 HO4S-2 Helicopter model to adorn my 1950's subject. Shapeways has 'em, and the main rotors too, but I only want the one and I don't feel like waiting for an eternity to get it. What to do?"
Maybe you want to tow a disabled fishing boat?
Well friends, Good ol' Chris at tlarmodels.com has the answer to your most fervent prayers, and don'tchawanna know what it is?!?!
Sikorsky H-55/H-19/ USCG HO4S-2 WITH US Coast Guard decals included!
Markings for 6 different Coast Guard Chickasaw Helicopters from 1951 to 1960! (The paint job changed in 1960) This 3D print has window, windscreen and engine vents in relief to ease detail painting and make very believable 1/350 egg-beater! Yes m'boy, the decal script is slightly overscale, so you can apply the decals without using a friggin' microscope AND so you can show them off to your fellows and say "Since Rhiner can do it, so can I! Nuthin' to it!" Rescue hoist not included. That you add yourself.
So, you want floats you say? Wait one!
So you want to build an Army S-55 or USAF H-19A rescue helicopter?
Son, you're on your own.
