Fixing Type - if you have small mounts on either side of the frame’s down tube you need braze-on shifters, if there are no mounts you’ll need clamp-on (sometimes referred to as band-on). Some 'aero' frames have mounts fixed to the top of the down tube, for these frames you require top mount shifters for the correct boss type (see below). There are also 'Clamp-Over' shifters that allow front & rear shifters to be used on a frame that only has a single braze-on.
Shift Type - friction shifters don't click into gear when you change, when they do click it's referred to as indexed shifting. For this to work correctly you must use the same system as your rear derailleur, if you're using friction levers you can mix and match. You don't need to worry about the front derailleur as left downtube shifters aren't indexed.
Speed - the number of cogs at the back the right shifter is designed to be used with. This is important with indexed shifting but with friction shifters you can in theory run any shifters with any speed setup, although the right lever will need to be pulled back further to shift into the larger cogs.
Shifter Boss Type - the shape of the mount (for braze-on fixings only). Campagnolo / ISO is standard and easily identified by the flat sections on either side, usually combined with a square base for the backing stop plates to fit. There are also Shimano ones with a keyhole shaped base and much less common French ones that are round with no flat sections.
Boss Thread Size - M5 (5 mm) is standard for Campagnolo / ISO bosses, but Shimano bosses will often have M4.5 (4.5 mm) threads and the French bosses would likely have 5 x 1 mm threads.

Simplex Tourist 303 rear mech (or derailleur, if you prefer), hailing from France and in production during the 1950s.

Shifting system - friction means your gear levers don't click when you change gear, when they do click it's referred to as indexed shifting. If you have indexed gear levers they must use the same system as the rear derailleur, if you're using friction levers you can mix and match.
Speed - the number of cogs at the back the derailleur was designed to be used with. This is important with indexed shifting, but with friction shifters you can in theory run any rear mech with any number of cogs, but you are more likely to have issues running high numbers of cogs with mechs from earlier eras.
Max cog size - the amount of teeth on the largest cog of your freewheel/cassette can be no greater than this to work with this derailleur.
Chain wrap - subtract the size of your smallest rear cog from your biggest, then do the same with your chainrings, add the 2 numbers together and you have your chain wrap.
Chain width - generally speaking, derailleurs designed for more than 3 speed use will fit a standard 3/32'' chain, the exception being some Cyclo & Simplex models from around the mid 1900s.
