Grove Hammerhead stem

[1978]

Does anyone know more about these stems?
I have two, One of each in 1" and 1 1/8".
Thanks in advance.

Do you have genuine Grove Innovations items or are they like the one in the listing?

I have similar `clones' as in the listing.
Curious to know more about them.

The 'clone' one has this mark on the quill which I've seen before but can't remember what it stands for like an itallic "IL"...Japanese-made? An old, groovy stem though.

If that is an H & an L it will be Hsin Lung. A Taiwanese frame shop from the 80’s-90’s

Picked up another of these stems this past weekend.
1 1/8" with stylized NL stamp on the quill. This one has
no cable routing. Must be meant for v brakes or
suspension fork.
