This appears to be a 150 cm projector, not a 90 cm. They might be referring to the wavelength of the radar, but I'm fairly sure that's 1.5m. Maury Markowitz (talk) 13:50, 5 December 2016 (UTC)

After further research, this is indeed a 150cm, not a 90. The original text from the IWM is incorrect. Maury Markowitz (talk) 17:35, 19 December 2017 (UTC)

And also worth pointing out that SLC entered service in 1941, not 1942. Maury Markowitz (talk) 17:36, 19 December 2017 (UTC)
