I got the frame from a member in the UK, it was collected for me by my family and is stored safely with them. I've yet to see the frame as I'm in Spain and haven't been able to visit for some while, (Covid, Brexit rules, health issues). From the photo it looks like a 1&1/4" steerer tube is needed so I took a chance and bought a steel tubed Pep fork from Germany, again from a member here. I already have parts for the build, (V brakes, peddles, chainset, outboard bearings if needed, grips, bars, 9 speed rear mech shifter and a new chain.
Now that it is no longer viable to buy from the UK and ship to Spain I have been collecting parts, (again from members) for the build and having them shipped to England. Currently I have wheels, tyres, saddle, seat pin, brake levers. If I've guessed wrong re the steerer tube size I have a couple of forks, a headset and a choice of stems.
So sorry, there is no build thread at the moment but I did find your thread inspirational.
