Finally got 2 Mascot serials on e-bay. And past days were watching The Three Musketeers. At fist impression it was so dated (belonged to it's time), but then I found it very enjoyable and was even sorry that it ended. Started now with Hurracaine Express.
Yes, this serial exists on You Tube as a serial and also as a Desert Command. I find the serial version better, there is some flair with all this beginnings with explanations. So little by little you became adicted to such kind of things, which none of my friends by the way can't understand.
