The guy had a suitable NOS set of forks hanging around, does £30 fitted plus £25 if the headset needs replacing sound like a reasonable price?
Cranks look good.
What forks are they? £30 isn't too bad as you need a long steerer.
£25 for a headset including fitting is a little steep, but depends what quality we are talking about. I'd personally be tempted with a M Part cartridge bearing headset, my local bike shop sells them for a tenner and fit them for free. But otherwise, you can spend between £10-50 on a headset, depends what you want.
The cranks and aluminium rings to look a bit better don't they, pleased I went for them to be honest.
The forks I saw are, erm, ...black ones with a threaded steerer
. No idea what brand they are but I'm assuming they are steel and will weigh a fair bit less than the Mag21s and require zero maintenance (always a positive where I'm concerned). But for £20 and then £10 to fit I guess it's not so bad.
£25 for the fitted headset was for an aluminium one, but I only after one that works so could go for £5 less and stick with a steel one and I might use your advice to negotiate on the fitting charge, cheers for that
