Have this lamp an internal GEC snap starter or have a neon-argon in the arctube?

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Unfortunately, I can't see inside easily as the barium getter makes it difficult. Shining a bright light through it doesn't reveal anything obvious like a glowbottle starter as in the smaller Sylvania lamp, but there might be something in the base which is hidden by the getter. Maybe James or someone may know.

This Lamp has a Starting Coil and a Neon/Argon Filled Arc Tube which allows the lamp to strike on the Low Voltage from the Ballast without the need of a Ignitor or any Starting Device.

I thought that it have a snap starter, since it is a British made Osram lamp, and I thought it made in the former GEC factory.

back in 1989 when OSRAM took over GEC they did away with the Snap Starter as they were putting too much stress on the Mercury Ballasts, especially the Compact Open Wound Types, whilst the Snap Starter was heating up and Snapping Open, using the OSRAM technology from their German OSRAM & WOTAN Vialox Lamps they redesigned the Lamps and used the Arc Tubes containing Neon/Argon Mix, as they strike instantly and dont have High Inrush current unlike the older GEC Lamps did.
