thanks very much for sharing this mount

date appears near to 1982
if you are curious regarding a specific date for the cycle there are a number of places where a date marking may reside
these include backside of crank arms, wheel rims, hub barrels, portion of handlebar stem down inside frame, backside of brake calipers, ends of handlebar beneath hand grips
there is a guide here to reading any markings found, if wished -

frame -
this pattern of frame is termed a
berceau; it is a subpattern of a design called a mixte
it is construced with lugs & laterals bridge from the firm BOCAMA
its seat stay and chain stay bridges are from the company ESGE
---
can make no guesses as to actual manufacturer
letters marked on handlebar stem - suspect they are intended to be read as HJM rather than HMJ but do not recognise either way
doubt that this handlebar stem is original to the cycle
---
photo tip -
you have given readers eight images of the bicycle which is good
in general readers will gain more information regarding the machine with pictures taken from its drive side rather than from its non-drive side
of the eight photos four are from the non-drive side and only one from the drive side; the one drive side picture is taken at a shallow angle which limits the information which can be gleaned

other readers will be along shortly who are sure to be able to give you more and better information regarding this steed
