Bachmann BR Standard Class 4MT
 

I have just acquired a nice example of
BR Standard Class 4MT 4-6-0 75074 BR Lined Black Early Emblem BR1B Tender

But as it's second hand it's missing a single buffer on the tender anyone know of anywhere with such supplies

you could try markits they do buffers thats were a i get my stuff from. they are truned brass and only come in sets of 4 but they are very good and look good too. they cost about £5.00 pluss p&p you can down load MARKITS cattalog from there web page. the 4mt is a very nice loco from bachmann too
