Just like to say a big thanks to all those taking the time to help me out in finding out more about this frame, it's been extremely educational.
So just to recap, it's Merlin Tange frame built Aug 1997/8 in Asia/Taiwan which was Merlin's basic steel frame, that came with Ritchey dropouts as standard. Who produced more drop outs than the entire UK education system.
There is just one things I'm a little confused about that I'm sure you guy's can clear up, is tange a form of chromely or not, just with Anthony saying basic steel makes me think of something heavy, were as this frame is light weight and is the first bike I've owned in 20+ years, and I'm sure when we talked about bikes made of basic steel back then, was like the equivalent of a pack of bricks with wheels attached.
I've also noticed where the seat post enters the frame, it has a slight curve, which you can see clearly in the second picture i originally posted, is this consistent to a Merlin Tange frame of that period, because I've not been able to find another picture with the same design as yet.
So where do i go from here with this bike, the truth is I've been riding it the last few days and it's grown on me fast, even in it's present state, it's a smooth ride, it has XT rear Mech, LX front Mech and crankset, Rockshox Judy Race Forks i think dating back to 1999, Mavic XM Rims with DT Swiss Competition Spokes, hope front hub, and Shimano rear, Hope Hydraulic front Brake, Azonic bars and X-Lite machined headset. It's a light bike fast and responsive, and I'm 45 years of age, so somewhat retro myself, so we suit each other well

. So I've decided to give it the full works and get it powder coated, as the frame seems like the enamel has come away in places or something, as I've tried showing you in a picture. And whilst the frame is sent away, ill do my best in getting the rest cleaned up and serviced the best i can, so any tips on cleaning old parts again would be much appreciated. So all being well ill be married to this bike for the next 10 years or so

.
When i start, ill probably open a new thread showing progress and looking for any guidance as i go.
Big thanks again to you all.
