Bought a second hand bike but can't identify

Hello I am new to this so bare with me.

I recently bought a second hand bike on eBay ( I know why?)

Any way the bottom bracket is broken and seems to be an unusual size, think I might have bought a nightmare, the size Bottom bracket Is a suze 35.6 outside of thread of cup
Unfortunately on the other side someone had fitted a dodgy smaller sized bolt on the other side which doesn't fit and they used electrical tape to keep it in i beleive it is a standard british sized bottom bracket, I must add this seems to be a very old bike as it has coppets and may be from foreign shores. What is on the bike is as follows :

number on frame by back wheel 72108
Simplex gears
Balilla brakes
Ifm special handle bar
68 mm wide tube at bottom

Both bottom brackets are righty tighty

Any way my question is would any one know what make of bike this is and what bottom bracket I would need to get to fix it?

Am I able to tell what bike it is by the tube design? By the way bike painted all black don't believe it is nicked as no numbers underneath

If you think I am a mug for buying it fair enough

A 68mm wide bottom shell, in conjunction with both cups being right hand threaded, would typically point towards a French threaded bottom bracket, though there are cases of 68mm Italian threaded bottom bracket shells. English threading is ruled out, as the fixed cup would be left hand threaded.

thanks for the suggestion I am not haveing much luck with this as its hard to find bike shops in the uk that stock bits that are old and of a foreign make seem a rarity.

I have that same problem, in the UK your best bet is to keep checking ebay, there is lots of fairly cheap vintage parts.

Hello Sorry yes the cup was measured at a bike shop, no marks on tthe bearing cup unfotunately, I measured the tube at the bottom with a plastic ruler so not very scientific but it seemed to be 68 mm

thank you for your help

The rear derailleur appears to be a Simplex S001 which place it no earlier than 1975 and means it is probably French. However, to be sure, measure the outside circumference of the down and/or seat tube. Bicycles with French threading typically used metric tubing while Italian and English threaded bicycles usede imperial tubing. Take a 1cm by 10cm strip of paper, wrap it tightly around the seat tube and mark where it overlaps. Measure the distance from the end of the strip to the mark. Repeat to ensure accuracy. A metric down or seat tube will have a circumference of 87.9mm while the imperial versions will be 89.8mm. Using the paper strip method you should be accurate to within 0.5mm.

There is a slight variation in diameter of axles (proper term spindles) and the holes in the cups. While they may seem to fit OK, more problems arise from slight variations in the diameter of the races (surfaces that the bearings run on). Sometimes it's possible to mix cups and spindles, but that it not always the case. If the bearings ride too high on low on the spindle races it results in insuffcient axial or radial loading, which accelerates wear. Unfortunately, mixing cups and spindles is primarily trail and error. It's best to stick with matching cups and spindles, if you're buying by mail.
