Good Day dougie995 and welcome to the forum.
Certainly late enough to be a Holdsworthy product.
Funny that person stamping serial got the numeral eight right side up on the steerer and upside down on the shell.
Readers would need to see more images of things such as sideview of head, seat cluster, dropouts. Also a full side view from the right side would be helpful.
One frequently encountered road model is the Torino. This is the Butler version of the Holdsworth Mistral.
