Hi Crew looking for a set of drawings on the 4.5 inch Mk7 rocket Launcher as used WW2  fwd deck on some naval vessels two banks of Five each unit holds 12 rockets any and all help much appreciated tassie48

Based originally on the Mousetrap and similar basic build. Look up "Old Faithful" rocket launchers. Mainly for beach bombardment. Can't find any drawings but plenty of photos.

TonyH that's my problem tons of photos even found the original ship LCS35 on you tube and loading the Mk7 rocket launcher have a couple of naval inquiries awaiting reply seems a simple pipe frame holding the 12 rockets just need 1/24 scale drawings I found a cad drawing even emailed to designer as well trust all is well over there tassie48

Not sure if John Lambert drew a setbup

Possibly look at the army side rather than navy? Try https://en.wikipedia.org/wiki/4.5-Inch_Beach_Barrage_Rocket and the Rottman book is gettable from Abe Books for about £15.00 so should hopefully be about the same for NZ plus delivery from US OR Amazon do it on Kindle to have a look-see!
Just HOW MANY WEAPONS ARE YOU FITTING!!!!!!!!!!!!!! Gregg?????

TonyH the vessel is LCS L large mk 3 #35 In 1/24 scale all 2 metres they were called mighty midgets single 40mm fwd 10 mk7 rocket launchers on fwd deck, twin 40mm behind and above fwd pair of 20mm on superstructure aft pair 20mm on deck and another twin 40 mm down aft oh yes 4 .50 cals on deck as well so pound for pound these little ships did well, doing my research they had a surprising amount of firefighting gear as well , a few were like fire fighting tugs helping to put out Kamikaze attack fires towards the end of the war , she carries a huge winch and stern anchor on the aft deck and running 16 channel rc gear on this one tassie48

Nice one Gregg. The least I can contribute is this https://www.hnsa.org/manuals-documents/ordnance-gunnery-and-fire-control/ If you go into the Missile Launchers and Related Equipment Catalog section, then you'll find, hopefully, the answer. The following are 2 options anyway, one experimental and one I believe to be a runner! You'll have to sort out the firing controls and storage stuff but the storage is probably a version of the ones on the PCS.
Hope they help

TonyH many many thanks for that found the 20 mm 40 mm and twin 40mm measurements as well will keep that reference source for future reference now to scale up looking at shapeways printed ones and others for kits once again thank you buddy much much appreciated doing research makes it easier with a heck lot of help worked out the rc operation all three 40 mm and both gun directors all turn together once again many thanks tassie48
