<div class="PlainText">Hello Tyler,<br>
the three tiles 396 and 391 are old tiles not part of the RICH <br>
production, we shipped them to jlab just in case we didn't get all we <br>
need on time.<br>
<br>
The tile 432f6 appeared at some time in the possible candidate for <br>
purchase, but, according to my logbook, was not purchased. There could <br>
have been a mistake in the shipment and we received it instead of the <br>
436f6.<br>
I should check with the producers.<br>
<br>
The missing tile 430f0 is strange. Could you please check if you have <br>
any log of the inspection at arrival? It should have been shipped in <br>
August 2018.<br>
<br>
Thank you,<br>
Marco<br>
