Identifying bike

Good morning,

I am looking to restore my dads bike - I believe its a 1960s bike. It was restored/updated in the 1990s. I can remember it had campagnolo gears (think was gran sport) as i can remember the smooth jockey wheels and recognise it. On a Facebook forum i have asked about the make as i can not find the makers badge anywhere - a reply was

I have a small collection of head badges including one of these, The Service. I think it came from the Wearwell Cycles factory at Alverley where my father worked for a while.

Can anyone lese confirm this please and ideally let me know colour it should be and spec??
thank you in advance

the wording on the badge is 'The Service' and England

Is this something that someone may have built for the British Armed Force's??
