OK, I am set to do this at the City University of New York on Staten Island. The best part is the Dr. there was so intrigued that he said he will donate 4 hours to us for his own scientific curiosity! He is booked right now but asked me to call him back in 2 weeks and we will shoot for first week in Feb. Since I will be at SOS I wonder if a presentation there is in the making...
So this gives me time to collect the pieces and plan the research. He said to expect 30 minutes per piece for a total of 8 pieces. I would like to do:
1) K&Q RK (my friend's)
2) SEBA RK is you are willing
3) 65 EK1
4) Fake EK1 (I have one on the way)
5) 1914 EK1 for comparison
6) 1870 EK1 for more comparison
7) Daisy PAB to see how this works on war badges
8) Fake Daisy PAB
SEBA - are you up for it? We can talk at the Union show...

The fake EK1 is wrapped and ready to go on Friday to you.
For the UK contingent here, anyone have want to set up a session with a SEM in London an maybe do a few tests??
TOM, I am 'dying' to test that K&Q '57er RK I picked up and see how the trace reading compares with the results you got on your '39er!
Harry,
I have a K&Q RK that would be a possible candidate ,it is en route as we speak,its just the cleaning that worries me a bit,can someone put my mind at rest re this ?
Have you contacted any Uni's yet ?
I know already mentiond but a mint mm 26 EK1 from the stash found in russia....since this is accepted as orginal with some negativity by others...and a worn war time EK 26....oh yeah the two differnt needles/hardware found on the 26's would be cool to compare also....
I have a 26 I can test from the "Russian Hoard." It all depends on time. If we get moving and the dr. is up for it, well, I will take my whole collection with me
I discussed the carbon or gold coating with Warren at ISU. He said the purpose of that is to prevent charging of the sample and creating some from of electric field or disturbance in the device. I asked him to do mine without the coating and we would see if it worked. It seemed to work fine without it.
As far as the advantages of SEM, it can focus in on a small area, free of contamination. If something analyzes over a broad area, it will pick up contamination of carbon, patina (oxides), and silica (dirt), and iron oxide (rust). The advantage of SEM is being to select a "pure" area free of contamination and measure the part we are interested in, be it paint or metal, without adding contamination in the elemental evaluation.
When preparing these samples, I shot from the hip and used the advice of the guy at the SEM. I used a mild auto soap in distilled water (kind of like washing your dishes) and lightly scrubbed the surface with a new toothbrush with soft bristles. After cleaning, I rinsed in another basin of distilled water and scrubbed with another tooth brush to remove any surface soap. I dried with a paper towel and a blow drier on low heat, using photo gloves each time I handled the medal. I placed the medals in a zip lock bag to prevent contamination.
Craig,
She shares all the die flaws, so I am not worried. This is just to enlarge the data pool and show correlation with Tom's RK. This will supplement our traditional analysis, not replace it!
