I have three wind up jacks, 1 with the 'boxed' in piece for the handle as such and 2 which have just the flat metal fork so to speak.

1 is well worn and has no markings on it but the other one is fairly new if not nos and has a warning sticker on it as well as a typed manufacturers tag. It's from W.H. Wylie & Co in S.A. and has the capacity and the low and raised height measurements as well as a warning typed on this label that's stuck on the jack.

Can anyone here ID this and tell me what it's from? Was W.H. Wylie a supplier to GMH?

Any help would be appreciated, Tony
