white -

lug pattern BOCAMA Competition 83 with cutout Nr. 1


shell appears BOCAMA Professional -

​​​​​​

crown appears BOCAMA as well but would need better image for specific identification

combination of BOCAMA lugs and Shimano SF frame ends suggests possibility of a Belgian origin

the domed stay ends suggest a product which is more "production" than "artisanal"

fluted seat stay caps appear they could be a Columbus item

brown & white -

yes, Italian threading suggests an Italian origin, however there have been cycles produced in Mexico & Belgium with this standard

there are also artisan framebuilders in the English speaking world who employ it. one such we have in my area is Albert Eisentraut (mentioned as example only).

lots of mixed messages here: full sloping crowns had gone out of fashion by the time recessed brake mounting came in. brake bridge appears it may not be made to accept recessed brake mount. we see investment cast bridges and lugs yet seat stay cap is a simple unpretentious one. shell is also the BOCAMA Professional. certainly appears to have received a measure of reworking. doubt all braze-ons original.
