I just received a couple of Jedson catalogs on CD from a fellow on eBay. The Jedson name was in use as far back as 1930! I think this will help boost the "vintageness" of the Jedson brand.
I asked the provider of the catalog information if I can post some of the content on the blog and/or the jedsonguitars.net website. If I get an approval, I will post the interesting content.
I can tell you that one acoustic guitar model looks just like my F907 except that it has a tailpiece. I suspect that Jedson made the guitars in house back in the 30's but outsourced the manufacture around the time Dallas merged with Arbiter. Outsourced to Japanese guitar makers obviously.
As you might see from the recent posts under the "Post here if you have a Jedson Acoustic" topic, Ian and I have concluded that several of the 70's Jedson acoustics models were made by Yamaki in Japan.
