Not sure,it had a reynolds renovated sticker on it when I got it,which I have replaced along with the HH stickers from H Lloyd cycles,they tell me the renovated stickers date from late eighties . So it was tatty in the late eighties and needed re painting,the stronglight crank may be seventies to early eighties,as could the ideal leather saddle.
Unfortunately the current HH shop has no records of build dates for their founders handbuilt .
So 70's or 80's maybe Anybody care to comment?
