Name that Benotto!
 

Brought this puppy home yesterday. Previous owner had tried converting it back from a flat bar conversion, before he gave up.
Model and year help will be appreciated! Info is hard to find.
Has the "M.R." mark by all the name stickers, so I've read that means Mexico.
Benotto marked front and rear dropouts, seat stay caps, fork bridge and head bearings.
Heart cutout bottom bracket with serial number 175
All three main tubes have been flattened (aero!)
Seat post is 26.7
Nutted, unlabeled brake calipers and a Thun crank.

Nice. We took a vacation in Mexico City this past February, and it was one of the common brands of bikes I saw.

are the seat stays diamond shape (5000) or round (3000)?

1987ish, by paint and memory.

I almost bought a blue & white fade one from the SDSU bike shop, but went with a Peugeot PH501 Ventoux instead. Felt better under mine keister. (Wrecked it in a ~25 mph solo crash. Now-unreliable memory says that I miss that bike to this day.)

Seat stays are round > oval - not teardrop like Columbus aero, maybe just a squish like the main tubes.
Wheel stays are round > football with no clearance crimping needed for wheel or crank - not diamond

3000's had diamond stays. The Mexican Benottos are a bit of a minefield.

I'm an idiot at (most) times.

I meant chain stays. Thats Mr DeRosa's contribution to cycling. And with the heart, he may have designed and made those in Italy.

DeRosa came up with the stiffer diamond shaped Chain Stays
