They very much do resemble Kay Vintage-
Another bass I sold (damn!!!) was a Fritz Bros made Kay Jazz Special repro:

Mine was sunburst, sorry no pic- It was cool.
These were/are 31" scale, extremely well-made, but TBT, the Spectrasonic was a much better bass.
(Sorry, Roger Fritz).
33" is an awesome scale- The best of ALL scale worlds- short 30" medium 32" & standard 34".
I have a Japan-built Aria Pro II IGB-RC, also 33" scale.

Super easy and fast to play, but without the short-scale "feel" which never meshed with me.
YMMV, etc. (Don't want to ruffle any short-scale bass lovers here!)
