Do someone Remember ORTAG GmbH?
A german company that in 1970s proposed low cost modular launcher, build from cheap materials and propellants.
probably not since there efforts went nowhere...
Now the US Company Interorbital Systems (IOS) retry this with there NEPTUNE rocket, but with a twist!
The hardware used in NEPTUNE is based on french Diamant A rocket
The vehicle is build from "Common Propulsion Module" (CPM)
each CPM has three tanks, one for Helium, one for white fuming nitric acid and one for propellant turpentine (yes you read right)
The CPM pressure fed the engines: either 7,500 or 15,000 pounds thrust (Engine are Ablatively Cooled)
According IOS webpage
one CPM 2.0 - 145 kg to suborbital 310 km apogee
N1 - 6.3 kg to 310 km polar orbit using two spin stabilized upper stage, Again this like french Diamant A rocket.
N3 - 20 kg to 310 km polar orbit
N5 - 50 kg to 310 km polar orbit
N8 a Long launch vehicle, with 500-kg payload into LEO and a 100-kg payload on the surface of the Moon.
IOS offer Two mobile launch options, to launch from any land location accessible by road or any ocean location.
The Mobile Land Launch System (MLLS)
The Canister Ocean Launch System (COLS)

CPM test launch, note how launch configuration is similar to french Veronique sounding rocket !
