Is this 612nm? Military He-Ne tube from auction site

Hello

I stumbled upon an auction with a disco laser made from military he-ne tube. On the photo it doesnt look red, can someone who knows better tell me which wavelength it is?

LASER DYSKOTEKOWY zbudowany na bazie lasera z pojazdu wojskowego ! Bochnia ? OLX.pl

Thanks in advance. If its really 612 or at least 59something (yellow one) I would buy it in an instant

UPDATE: Now I am almost positive its 612 nm, just need someone to confirm it
