Orrell frames are great - I know, I've got one! They're very well made and lovely to ride as you say.
I can't remember how much you had it on for but the price seemed very fair to me.
I'm pretty sure it will be either 531 or 631 - Neil used 531 until it ran out then switched to 631. I've never heard of him using 525.
If you want to find out for sure give him a ring - he keeps details of all the bikes he's built and is happy to share if you give him your frame number. 0161 681 1517.
