I'm no Limongi expert, but his frame details were extremely varied, yet nothing seen on this frame jumps out as typical with any of the examples I have seen online.
I don't know for example that he favored Silva frame bits (brake bridge and/or BB shell), and tho I do see one that has this fork crown, many do not, and have not seen any with that staycap treatment which is distinctive, but then Limongi did a great variety of seat clusters, quite a few fastbacks.
Maybe one of our Canadian members have some more experience with ID-ing Pepe's frames. Are you located in Quebec, @

Note: if 26.8 is the correct seat post size, then this is not Columbus SL, might be Aelle, might be another brand
