Description

Arnold Salesman sample Tin toy RARE Germany Log Cutter, Grinder, Saw,Pounder. Condition is "Used".
I have researched for years and have never found another one like this. Was told it was a salesman sample. You can find the individual workers on separate bases but could not find another with 4
One crank works all of them. Rubber bands will only fit on end pieces. There must be away to contact the wheels with some other type of material unless you take apart which I will not do.
I have the original brown box it came in but the lid is in pieces
This has a patent applied for in US Zone Germany 1945-?
Other single ones are listed in the 20’s but may not be
If you want more photos send message
There are a few slight scratches on gray base but people and tools seem to be mint
Thanks for considering this purchase
Measures 11 1/2” wide 7” Deep
Piece of box lid says 1/12 of a dozen 630 Arnold
Noted was text that this may not be a salesman sample and that it can be ran from a steam engine as well as the crank motor. Thank you for the extra information
