How can you tell real calc bubbles?

They sparkle and should have a raised edge on the underside of both lengths where it attached to the board.

No stupid questions, but if you can't tell, then what's the difference...?

This is semi-rhetorical -- I KNOW we have purists out there. ;)

Well I can see how its good to know; if you are planning to buy what someone claims is the real thing.

I bought what was claimed to be real calc bubbles... and now I know that the raised edges and increased thickness (that do not appear on the Blastech version) prove that they really are real. Thanks everybody. :)

well mine I know for a fact the it is real cuz I bought the whole calculetor. It got it for .50 at a yard sale. I've takein it apart now and got the bubble display out waiting for me to make a saber. I've acturaly going to copy it so I can have however many I want. I din't see any differance between haveing the real thing or a copy. Copies are cheaper in some cases and easier to come by and they look just as good.

They are thicker than most repros.

Any other size difference? Do they fit better in a Graflex clamp than Blast-Tech's reproduction?
Are they wider?
I wonder also if the plastic is different. Blast-Tech's scratches easily.

Gone but not forgotten.
Copies and repros have their place...but I don't agree with the aguement that they're just as good.
The magnification properties are fantastic in a real set of bubbles...you just don't get that sparkle from a repro.
If you in fact have a real set next to a copy you can tell the difference without question.

No, in fact the copies fit better than the real thing...
I've sort of clamped the bubbles between the jaws, instead of sliding them under.
They're much thicker than the replicas made for a saber clamp.
They take a little work and minor modification but they're well worth it.

I have a real one and it is longer than the replicas I have seen. Most if not all replicas are cast to fit the length of the graflex clamp. A real one will have to be trimmed to fit perfectly. Mine also has little posts on the bottom where it was attached to the circut board as well as the already mentioned slight ridge on the underside.

Real ones will be a flawless casting, while some repos I have seen have some minor imperfections in casting.

The real ones have the small wire Light Emitting Diodes wiring in them. Thats a dead give away more than anything else.

?? Not sure what your talking about here - the LED wiring is spider webbed over the PCB, not attached to the bubble strip.

In fact, I tried to replace the bubble strip in a calculator with a replica and smashed all the spiderwebs together - now the lights don't work too good. :cry The wiring is very fine behind the strip, be careful if you plan to use the calculator again at a later date.

The one thing I never like about these types of threads, (real vs. repro anything) is that every time we point out all the differences and nuances, there's a chance there's someone out there making a note of them and using the info to make a better fake to pass off as the real deal.

For instance, we've gone over the graflex with a fine tooth comb in the past. If a bootlegger was smart to collect all the information we've put out there, they could easily could produce a dead-balls accurate repro that could easily pass for real.

The need for super accuracy can be a dangerous double eged sword.

Sorry for the rant.

I seem to recall that the Exactra 20 calculator also appears under another brand, but I don't remember which brand and model it was. Does anyone else do?

Real bubbles are CRYSTAL clear. I've never seen any replica even come close to the clarity of real ones. If I can capture the clarity between mine and replicas WITHOUT removing the tape from under them, I'll post pictures.

It was a european version I think.
