antique drinks trolley

Antique 2/3 tier drinks/tea trolley with a double sided drawer on the middle tier. The trolley is mainly made of a dark grainy wood but had brass or bronze trimming, drawer handle, wheels and handle ends. The bottoms of tier 2 and 3 are covered in red felt. I have searched all over the trolley for some sort of identifying name make or number with no success except for the letts D.R.G.M and an engraved love heart with the initials S.W engraved on both swivel axels of the 2 small swivel wheels. From what I understand D.R.G.M was a german stamp used prior and during WW1 and WW2 from 1890 through to 1950 and that the initials S.W are a mystery, noone knows who he/she is that is all I know about this beautiful cherished and extremely well kept piece of craftsmanship, so if anyone has any information about this item I would love to hear from you. Thank you for your time and assistance. Benjarman.

Excellent
