Found this little guy in a small antique shop the wife and I visit occasionally. SAE date of W3-79. I am curious as to when these were made as every TB 7-07 I have ever seen has a W3-79 on it. Never seen an earlier date or later date. I know these are rebranded Deitz and they are very comparable to a Fireball. Kind of a mix between the FB1 and FB11. Just as effective and definitely quieter than the early Fireballs.
