I'll have to try and track down the caddy pack... but I'm not interested in unlicensed or unofficial accessories.
NEC did have a catalog filled with accessories, from watches to shirts to mugs to SOFT PACK TurboExpress cases to hats to wallets
It was official, through NEC.
An old thread has scans...it was a fold-out pamphlet really.
Now, the HARD CASE TE And TG-16 cases...I don't think they were first party, but licensed., but never advertised in any catalog consumer catalog that I know of.
