I'd like to see how far this mod has come 

I tried, cheese more

 I think I have some older 1.6.4 versions lying around somewhere.

But if you just want to know what the mod looked like way back in the day, I believe DanTDM did a review of the mod that you can look up, back when it only had a few daleks and little else.

The earliest versions were on 1.5 (or 1.4? I can't remember), all of which John has somewhere in the mystical jungle that makes up his storage drives. Earliest once I've actually used was 1.5, it was fairly simple after coming out of Pigman+ with just a few Daleks but it was good, and had a lot of cool tiny features that we don't even have now.

I have version 1 for 1.4.7 (I think that's the version)

However I also have somewhere an earlier 1.3 version which was never released

Oo , a download would be amazing , I would love to see what the mod started out to be

I Would Love To See Version 1, Or Even Some Pre-Version 1

 omg, checking the 1.3 version out would be sooo cool!

I have a version of the dalek mod for 1.5.2

 could I get the jar file? if not, that's fine
