That's a 1993 built frame, so likely to be a 1994 model. If you can find a catalogue, that may list the OEM seat post size. Or another member on here may also have a 1994 Ascent and can check their bike for you.
My Axis is different tubing and factory - so that won't help.
I'm pretty sure that there is a nicely upgraded Vantage on here already, from a couple of years ago. They can certainly look good when sorted out. See if you can find it. I love to see an underdog given a once over.
I mean it looks like one, but the frame number doesn't seem right.
Frame number is M8F11913
Looking for something to replace my Holdsworth Equipe and found this.
Here's a few more for you:

I can't help with the identification, but the frame number format is the same as my unknown 'DBR' frame - link in sig. Mine starts AM96 .... It is an unusual format and this BMX frame is the only other frame I have seen with the same type of number.
I have two Oranges listed with 'MT' on my list. Both are P7s. So it seems based on this small sample set that yours is also a P7. You might want to contact Orange to see if they can give you any history - please update this thread if you get confirmation either way.
Got a pair of very nice/mint Manitou Mach 5 Stanchions - I can add pics if there is any interest.
No marks or scratches that I remember.
£20 plus post.
They've been sitting in a box of Marzocchi spares for several years and I don't think I'll ever need them.
Fairly certain that this is a Ballistic X-Ocet ... Frame number suggests it is 1998 built.
Most often seen in blue in the UK. Where are you based?
