This is the FT401B, the last model in this series. There were no great improvements over the FTDX401 apart from adding 160m
This one works and just needs an alignment check.
Unfortunately someone had resprayed the outer case black from the original grey.
This is the FTDX560. Older than the FT401B, the FTDX560 was a "base model" of the FTDX401. The '560 had many optional extras which were all included in the '401
This one is in good and original condition and works. It just needs an alignment check.
This is the front of the original sales brochure for the FTDX401 sometime in the 1970s
