Late 1920s Eveready Model 1 TRF Set need info

[vortalexfan]

Hello everyone, today I found on Facebook Marketplace locally a late 1920s Eveready Model 1 TRF Neutrodyne Radio with its original matching speaker attachment for $75 and according to the owner he says it needs to be rewired and the speaker's cone is torn (to what extent it is torn I am unsure, but more than likely it should be easily repaired by just using brown coffee filter paper and diluted Elmer's Glue).

My question is, how fair is the asking price (I haven't gotten it yet as I just messaged the seller about 45 minutes ago and I more than likely won't hear from him until tomorrow) and if its not a fair asking price what should I offer him price wise?

Also how hard are these early TRF Neutrodyne Sets to repair? I'm asking as this would be my first TRF Set I've ever repaired.

Any help or advice in this matter would be appreciated.

Thanks.

P. S. I do have the pictures of the unit in question from the Facebook Marketplace posting.
