The withdrawal of the registration statement was not so "abrupt" I don't think. The withdrawal of the securities registration for stock in the tape business occurred at the same time that TRTN (now JBII) entered into an asset purchase agreement with the tape business. Of course, merging the tape business into a publicly traded entity obviates the need to register the securities of the tape business for sale in the public market (i.e., the OTC).
Am I missing something? Is there a filing that suggests the tape business is operating independently of JBII?
As for tracking the cash flow of the tape business prior to the acquisition by JBII, I'm not sure how one would accomplish this, and I'm not sure why this would matter to a JBII shareholder who was not also a shareholder of the tape business independently of JBII. It would be an exercise in futility to do so, in my opinion.
