No, not really...well not in my opinion anyway... its from the very bottom of the range mid to late 70's... Actually, I'm not even sure if Holdsworth made the Cresta's... I think they might have been bought in cheap frames... certainly the lowest standard that they (Holdsworth) ever stooped to .
And yes I know there is a red one on eBay for £999..... but personally if it was on my doorstep I'd give maybe £20 as the Selle Anotomic saddle could possibly be worth that alone.
Yeah, sorry...I was being a bit dismissive.. that group set is worth a few quid..didn't spot it.
As for it is... my money is still on the Cresta, they all had hand built holdsworthy stickers (can't remember where I had read the rumour about the Cresta frames, sorry)
Cresta, Jubilee & Majestic all had this sort of under top tube arrangement for the rear brake cable up until 1980/81
This period (pre 1981) the Colstar & Competitor had top tube clips.
Post 1980 they all had the triple straight through for outer cable guides in-line on top of the top tube.
PS. It would need to be all double butted inc forks for it to be the top of the line Colstar.
The 70’s & 1980/81 Cresta & Majestic definitely had pump pegs in front of the seat tube. But sometimes between 81 & 83 they were dropped (certainly from the Majestic) And I’m pretty sure both had main tube plain gauge 531
