A pair of Klein Quantum framesets

I went through a period of buying decent conditions on sight, which has resulted in a lack of space. I would like to buy a particular Quantum Pro (once one becomes available), so it is time to get rid of a couple of framesets that have been sat unused for a few years. I will be at St Pancras/Leicester/Manchester/Glasgow in the next few weeks, otherwise I can arrange postage at cost. Not really sure how to price these, so will gradually drop if there is no interest!

53cm 2000 Klein Quantum frameset in Purple Haze. I rode this for a while in a silly build, but it has always been too small and my back hurts just thinking about the stack. My wife then adopted it, but it's sat in a storeroom for a couple of years since she got a gravel bike. Personally, I think it's in pretty great condition. There's no bubbling/dents and it has never seen a wet road under our ownership. There are some minor marks consistent with a 24 year old frame (tried my best to photograph them although actually fairly hard to see IRL due to the paint colour) - think some will actually buff out. Comes with derailleur clamp and Cane Creek headset. £360

55cm 1998 Klein Quantum race frameset in Caribbean Linear Fade. Bought on a whim a few years ago but has sat unused. Again, has some minor marks, the worst of which are on the chainstay from chain drop, but there is no bubbling or dents. Comes with Tange threaded headset. I bought some super-light and quite rare threadless Look HSC 2s as seen in one of the images and these could be included in sale for an extra cost if required (I will list these in classifieds also). £320 or £400 including Look forks

What is the headtube and the top tube length on the smaller one please?

HT is 11cm and TT 54.7 c-c

Are these based in the UK or abroad?
