@vecchio Thank you for your kind words!
Sorry, but I would have replied earlier, but I was enjoying time riding the hills of my childhood on classic bikes made in the era of my heydays, and I am not going online very often anymore.
I am curious as to where (bike shop, online sales, online forums, etc.) you saw Lloyd bikes/frames?
Presently I am only aware of a small number (if I recall: 3 photos privately owned, including mine; 2 or 3 privately owned anecdotally but no photos; photos of a privately owned track bike that was supposedly built & ridden by "Chalky"; photos of a track bike from an ebay seller. So photographic evidence of 5 frames but by "Chalky"; & maybe another 3 still unseen. Anecdotally, he had only built about 3 dozen frames, and only a portion of them would have been badged as Lloyd frames so they are a rare marque to find in general.
I ask because frame is pretty much unique other than those other frames with Lloyd decals (the "Chalky" track bike has no identifiers). It would be nice to get a better scope of how Mick built, and the commonalities between frames (lugs, braze-on fittings, frame materials/drop-outs, detailing/engraving).
Regarding "Vanni" Losa, I am not sure why he did not badge many frames under his own name other than to assume that he was too busy a man to be building frames badged eponymously. He seemed to nearly be a one man factory (other than helpers) considering how many brands his frames were sold under. He built frames for various marques and teams; some outside of Italy.
I assume it was his choice to do contract work and he may have found it more profitable and/or enjoyable to work as contract builder and not run a full scale business which takes more time and staff. Although I am mostly familiar with Italian builders, I assume that many French, English, and other countrys' builders (e.g. Carré, et al.) did similar work since it was not uncommon amongst Italian builders like Losa, Pelà, et al.
