I think the trolling issue has already been explained
If I buy equipment I will definitely show you everything and measure but I have to know if it is worth it. The thread A vs M vs H read and nothing there actually does not have about 130. I can buy the device A130 or M130 or A140 or A131 or A130V for the same price. The question that will be the best. And all the fun in this would be to undress yourself. I am a passionate elector and it will be fun for me
"but I have to know if it is worth it" --what does that mean/what do you mean by that? "Worth it" in what way?
You are 10 years too late---those individual diodes are worth nothing to anyone here----is what everyone, so far, has been telling you repeatedly
Buy whatever you want to buy and use your spare time as you see fit, for whatever reasons.
None of your choices are worth anything to anyone on LPF nor really anywhere else that I can find so..... Maybe if you can get the projectors for free or $10 to $20 each you could maybe sell complete working arrays as replacements for old projectors if you can find a customer. Most people throw 10 year old projectors in the garbage can and buy a brighter and more current model.
What you do is up to only you--all your listed choice are yesterday's rubbish nobody wants so.....pick one.
You keep going around and around in circles with the same question and you have been given the answer many times---the A130/A140 series are a waste of time and money-- they were something to consider 10 years ago--if you are obsessed with buying one of those projectors look for a new or low hours used A140 and you have a chance of getting slightly stronger brighter binned diodes or mix of stronger and weaker.
Nobody has been even slightly interested in A130/A140 diodes for years--they are worthless/worth nothing --are just historical curiosities--they are ancient, a relatively inferior generation diodes whose day and usefulness has long been over--no longer produced/manufactured.
If you have to buy one then buy one if they are worth it to you--they are not worth the time of day to anyone else. If you pay more than $20-$50 for 130 projectors to harvest the diodes it is too much $s, unless your time is worthless.
M140 A-types and M-types which some people are still interested but are hard to sell and very few even bother with them. are available for <$10 each on eBay so your 130 series might be worth $3 to $5 each if you can find anyone who wants them and it will not be easy---see:

"This listing is for FIVE M140 A-Type laser diodes. The diode emits a 445nm wavelength with output power reaching 1.8 watts. Each diode is carefully extracted from a new or low hours laser diode array. Each diode is tested in a heat-sink'd module to ensure functionality. Rubber boot may have been removed during testing. Please inform me if you would like it included."
PS Here is a detailed statistical analysis, on another forum, done in 2011 of 1700 pieces of A130 and A140 diodes:
