Sorry for late reply.
I have had it a few years, there is no maker details on it at all. But I think it was a Sealey.
The angled bit at the front was a pain because the front part clashed with the discs when you put bike on stand so I cut the angled bit off
It fell into my lap - I went to buy an abandoned resto project off a disillusioned guy.
I bought the bike and he gave me the lift as part of the deal - it was like Christmas
When you have one you realise its one of the best bits of bike kit you will ever have
