Yeah, me to, my limit in the garage is 7 bikes at any given time and I seem to be always at my max with other people's projects and my own stuff. If it wasn't for my wife I'd end up on one of those hoarding TV shows except it would all be bike stuff... The neighbors bitching etc.

Excellent - work!!!
I have just pulled a TSUNODA Grand-Prix from out of a skip in Bracknell, it looks very similar to yours but the gear levers are set on the handlebar stem.
Could you let me know where you got the replacement stickers from after you resprayed your Tsunoda please?

Hi Martin,
They are nice bikes, I find the ride very smooth. With regards to stickers I took photos and measurements but haven't had any done. There are lots of places that can create them for you. I quite like the clean look of the metallic respray without stickers, I did save the badge though, drilled it off and riveted it back on after the respray. Some Tsunodas have the sticker front badge instead of this aluminium one. Let me know how you proceed with it, post up some pics here of current state if you can.
Cheers
Tom

Forgot to mention Martin, if you are looking for the date of your bike then this website might come in handy, your serial might be on the bottom bracket like mine. Depends on model.

Outstanding work! The transformation from the before pics is amazing. The excellent fit and finish on this reflects hours of dedicated hand work. What do you use for paint? the finish is very clean. Also; did you strip or sand blast it? Thanks for sharing and saving this gem from a dismal end.

Hi Velodoc, sorry for late reply
Thanks, the original paint was sandblasted. I had used a blowtorch and scraper but was doing an inch every ten minutes! That paint is seriously tough... I took the frame to a backstreet auto repair place rather than a bike specialist, and chose a colour they would have left over after a car repair, Turned out really nice. I still love your restoration work btw, I wish I had more room for extra bikes, missus would kill me :-(
