No, sadly not, as mine are sweet FA like that. They might be off a Renault 6... welcome to kit-car hell... they might be off an early 5.

Bleeding: Gunson's eazi bleed - piece of cake then! Don't try it until you have the drum and shoes on - unless you clamp the cylinder so it doesn't just pop out
Reuilding: Take a photo before removing (oops!); copy the other side. Are they auto adjusting? Should just fit up, adjust it so that the drum just slips on, bleed the brakes, then stamp on the pedal a few times which should then take up the slack in the adjuster. Shouldn't be any need to re-bleed.

They look like the offset peg adjuster type shoes you turned with a square ring spanner, I know they would have been on more cars than just Renault.
