It interests me that both the eBay bike and your bike are badged as Hawthornes. This specific frame was never shown in the Montgomery Wards Catalogs and until the appearance of these two bikes, I doubted if was ever offered as a Hawthorne. The earliest catalog (Rollfast) references I have seen of this frame show it without a tank and marketed as a Heavy Duty version of the more common rainbow configured version.
Since I can’t view the bikes in person I have to draw my opinions from photographs which are good for most part identification but inadequate to form conclusive opinions on provenance. It is possible that both the bikes have been rebadged as Hawthornes but it is equally possible that they were sold as Hawthorns and not cataloged or only sold through MW retail outlets. The impression I get looking at the photograph of your bike is that it has been pieced together by a previous collector based on some of the parts and the varying patina on them.
As for the specific details and parts on the two bikes:
The eBay bike uses a collet system to lock the seatpost into position which was a 1936 only design, your bike has a standard pinch bolt clamp. The eBay bike has a chainring with eight comets which is the pattern that Montgomery Ward used on Hawthornes from 1936-1939. The chainring on your bike has five comets which is the pattern used on later Huffman built bikes so it is a transplant. Another difference is that the earlier eBay bike has the earlier flat-top fork crown while your bike has the later domed version. This difference is appropriate given the age difference of the two frames.
The eBay bike has a lot of non-factory parts on it including the handlebars, the chainguard, and the generator. I believe in the rear fender because it still has the spacers that were used on early Snyders so the factory could build the frames into either 26 or 28 inch variants.
The eBay bike has an appropriately un-braced rear stand. The braces on your stand mean it is from a Colson or a Roadmaster and make it individually more valuable than the un-braced version that would have originally been on the bike but not likely to be factory original to your frame.
The bars on your bike look like the chrome is too nice to match the rest of the bike and Hawthornes typically used a clamped on brace bar rather than the fixed one on these bars. The year of the bike also generally predates the use of streamlined grips
The last point is the fenders, neither of these bikes has the flared tail on the front fender that I would expect, otherwise they look generally correct along with the braces that support them so that just remains a question in my mind.
All that said, it is a great find and many of the parts that I question as being original to that frame are probably worth more than the parts that would be “correct”. I’ve noted what I see to answer your questions and to be helpful in case restoration is something you are considering. As it stands you have a nice looking, complete bicycle with a rare frame. I would think that the overall condition of your bike coupled with good photos would bring an eBay sale price considerably higher than that of the even rarer 36 framed bike did.
