I compared two editions of the 'TBX-8 Preliminary Instruction Book' contracts
NXsr-38500 22 Apr 1945
NXsr-69224 15 Mar 1945
The second one shows the clear plastic bib, 'rainshield' but it does not as far as
i see, show up in the components list. The rainshield is not seen in any photo in
the earlier manual. Seems to me this much sought after accessory was only
maybe supplied with the very last TBX production, and not any earlier models
including of the TBX-8. I have owned about ten TBX's, only one set, unused in
trunk, had the rainshield.
