Pat the Guru Missin discovered a 1930 trademark for Boss Cracker by the merged and short lived Rauner/Seydel/Bohm companies. Koch, who previously produced the Boss Cracker the black sheep of the Crackajacks, had been sold the previous year to Hohner. It appears F A Rauner (Rauner manufactured the Crackajack brand) renewed the trademark of the Boss Cracker. The Boss Cracker continued to be sold, alongside the other Crackajack models, for four shillings up to and including 1934. This is around the time the short lived Rauner/Seydel/Bohm merger was dissolved.
In light of the new trademark, an extensive dive was taken once more for the elusive B C Dunlop and look what I overturned. Perhaps this supports my theory of Allan’s trying to cash in on the Dunlop name. However, wheels, or should I say tyres, would be J B Dunlop (John Boyd) domain and not B C! There’s no special system either, but there was a movement for system acknowledgement branding. Usually the connection was for obvious reasons like Albert’s System or Bohm System. Still no idea on the B C Dunlop connection with Allan’s Crackajacks, and obviously there was none at the time by The Bulletin reporter.
D.R.G.M. 102024 (Translated from trademark above) – Harmonica whose clothing covers, made from a single piece, cover the reed wood and are enclosed at the sides in the blow holes by corresponding punchings. Andreas Koch, Trossingen, Württemberg. 8/29/98.
Koch thought enough of their unique cover by providing protection not with a patent, but the less costly D. R. G. M. (Deutsches Reichs-Gebrauchsmuster).
He also had other models dressed in a onesie.
Clutching at Straws?
I have suspicions that this could be a onesie too. Difficult to tell without a real life model. Do you have one? Could you share a pic? Do you have an idea of who it maybe? There are suggestions that And’s Koch could be in the frame for Mick Simmon’s Perla. Interesting (not very funny) that the model is stamped ‘Large Harmonica’. This is not a phrase used ‘Down Under’ until quite later. The Perla disappears from the marketplace in 1929. This is when Koch is taken over by Hohner.
Koch’s Kangaroo
Koch also had The Kangaroo mouth organ in our country. Interestingly, the Trademark has a more upright kangaroo with a different tail configuration. For more on Kochies Kangaroo hop over here 🦘 and here 🦘.
Made in Switzerland too!

These historical information delves you produce are always fascinating in the research you put in. After I’ve read them, I often think of when the internet offers up detailed information from those who look for specific information of vintage and antique items. If I buy a Charity Shop find vintage fountain pen, for example, it is second nature for me to hunt for information concerning the pen.
Data Microsoft Table lists usually pop up. A few photographs attached too. They focus on a pen company, Parker, Conway Stewart, Mabie Todd, etc., and are the usual information sites that provide full on model information. They usually have very ‘dry’ details with no fun insights or background stories to one’s collecting or simple hobby passions.
That’s why your write up analyses are so good Shep. They bring the ownership to life. And they prompt the owner reading your research to look further into the stories. Gives the harp passion a fantastic personality.
Cheers for an interesting vibe again. Always welcomed. 🙏🏽🍁🍂
