Dear Marklin enthusiasts!

My family found this Marklin train in an attic a few days ago and we are trying to establish it's value. Could anyone please advise?

Thank you

Thanks you very much for your response! If anyone else would like to comment or add anything else that would be really helpful as I am not an expert in such old trains and their value. I have looked at the train very carefully and my instinct tells me that it is not counterfeit, repaired or tampered with in any way. I appreciate being able to use this forum because of my lack of knowledge!

Hi
I did some research and there is little information (pictures).
In the Märklin 1938 catalogue, the starter box is mentioned but without any picture
In the Koll's catalogue I have 1993, the loco alone is valued at 9000 DM
In the Greenberg's guide to Märklin OO / HO the SLR700 LMS is valued at 1500 USD

All agree there are many fake items because the price is doubled between a normal SLR and an LMS version.
On the coaches the check would be easier as fake lithographed steel is much harder to make.
Note: there are simple processes to make wheels shiny again so it does not mean anything.
Always be suspicious of a too new-looking item that is 86 years old. Also check for "Zinkpest" very common at the time especially on the coach wheels
Cheers
Jean

Thank you everyone for your posts and email replies about this find - my sister-in-law is taking the investigations further on from now, but I will keep you posted once she manages to get an expert eye to say whether it is counterfeit or not, also just in case someone here is interested in buying it. I appreciate and admire your expertise, and thanks for letting me post on your forum!
