rawboned

He was a big, raw-boned, hulking fellow from New Hampshire, and his laugh was like the braying of a mule.

The other was a raw-boned and grizzled woodsman, still-eyed, swarthy-faced, and affecting the Indian fashion of a buckskin jacket.

He held my stirrup, and then jumped on to a raw-boned beast which had been 'borrowed' for him by his friends, so he informed me.

And he would arrive to find some aged specimen, raw-boned and indifferent, waiting for him in the stable.
