They look similar to Parma 48 pinks.

They were marketed and sold by H&R.

Are they suitable for vintage cars with powerful motors?

Similar in quality to the Parma pinks?

We found that the material was very hard and the gears tended to be noisy. Also, a high percentage had too much runout to get a good mesh.

 

Stick to the Parmas, or better yet, the Kofords if you don't need the big diameters.
