Generic Asahiflex extension tubes

I have found a set of 3 brushed chromed brass extension tubes that fit the thread of my Asahiflex 58mm f/2.4 lens. From what I have read this lens has the unusual 40.3mm thread. The tubes are in reasonable condition and unbranded.
Do they have any value or do the only collectable tubes have the Asahiflex logo?
Would appreciate any advice.

Asahiflex extension tubes don't have any "asahi" or "asahiflex" marks as far as I know. A picture would help.
