Found a similar on ebay

Hi, looking for a front axle assembly, bought a loco with the knowledge it hasn't got a front axle assembly, I've looked a different locos from the same loco type but so far I haven't found a matching axle, whether the wheels are black or red wouldn't matter I always can paint it, the loco in question is an ÖBB BR 52 (3416) and it has a unique coupling but maybe a member has got more knowledge than I and may can help me locating such a front axle assembly.
I've looked on ebay but so far there is nothing similar., Märklin always brings out new steam locos and maybe one of these could be a match.

there is no spare part available from Märklin under that catalogue number

your help would be very much appreciated

regards.,

John
