    They are in someone else's possession right now, and they are not knowledgeable in them...

    Good as by the 70s most cylinders were made with 3/4 - 14 threads. But have whoever has them take some more photos - if the valve threads can not be seen they are 3/4, otherwise if one can see the threads then 1/2.

    They appear to be 3/4" - 14 but I don't see any Transport Canada (TC or CTC) markings on them in the photos.

    Thanks all. Seems I shall close the deal.... While not the "matched pair" I was seeking to but together a set of vintage doubles, it gives me 2x the chance to find a mate...

    These are not easy to come by around here...

    BTW - odds of lined? Seeing they have been maintained (in current hydro), I'm betting they are likely not....

    You might want to check to see if they have Transport Canada markings or if your fill station will fill them without as I believe you are in Quebec. Cylinders used in Canada should have a hydro test by a Canadian facility to be legal but probably not as much of a hassle.
