When did roll films begin having the start Arrow?

[Tel]

In the event my super old rolls don't have the arrow, I do have two very nice red window folders I can run them through.

Well... I've got the second best option- A Yashica 44. Just need to line the number 1 up in the window and I'm set.

Not a bad option--nice camera and a LOT less hassle to fix than a Baby.

First, I want to say I'm not sure if this is the right place to post this, so sorry if it's not.

Anyway, I noticed on a couple Verichromes (not pan), that there's no start arrow. So I'm wondering, when did this start to get implemented? I've got a 1946 expired 120 sized plus x, which I'd say would not have one, but what about a 1959 and 1960 120 sized Verichrome Pan?

I only ask because my Yashica Mat 124g and Mamiya c220 require the arrow to load the film properly.
If any super old film doesn't have the arrow, it's probably going through my modified Kodak Monitor.

(also, the old verichromes were 116 (which I bought pre exposed), and a 127 (using a Yashica 44, so I just need the numbers on the back).

I have to load and advance my Fujica GA645zi "blind" because the backplate screen is kaput. I have counted that 35-40 turns of the electronic winder takes me to the first frame and that 4 turns advances to the next frame!
