Pretty sure I have a new Weaver Model 90 base for the 39a. It is pretty much identical to the factory base as far as I can tell - it is grooved.
let me know if this would be of interest and I can dig it out.

NOT looking for the Weaver 90 base. Looking for the Factory steel base that works with 22 rimfire scopes that have the ring already on them to fit 22 grooved recievers.
