    Isn't it strange what aspects of enlightenment our hobby throws up during research, today I went looking at loco buffers and suddenly realized even something as basic as that isn't all it seems. Now here's my question can any of the chaps on here help with information regarding Oleo buffers as fitted to Sulzer Type 2 diesels, because I've just purchased an etch kit of the BR Class 24 from Steve Beattie and you have to source your own buffers, easy easy or so I thought having found the Roxey Mouldings website which offers two different buffer head sizes, one at 19 inch (scale) and the other at 22 inch (scale). So I rang Roxey and the man there was unable to say which size was used on the Class 24, I then found a website dedicated to making 4mm Oleo buffers in white metal and they said that the 19 inch Oleo buffers were fitted to early diesels such as Class 24 / 25 in the 19960's but the 22 inch Oleo's were replacements and fitted to other later diesels such as Class 47. I then messaged an old friend who now works as a driver training instructor for DB Schenker he told me categorically that the larger buffers were only fitted to Class 20's and 47's... he should know since he owns a 20 a 47 a 73 and an 03... now who else do I know that has such a large collection :scratchchin:. So my question is does anyone here know which size diameter buffer head was fitted to 24's and 25's?

    I've ordered a set of each size from Roxey so I'll have to wait and see if they are suitable.:confused: Anyway this is the loco I've decided to recreate and the buffers are quite distinguishable from the Oleo vanfit buffers. The engine is D5018 which was still in green in the early 1970's as I seem to recall, it is standing under the shunting bridge about to depart from Leek station yard with the 3N01 19.40 evening parcel working to Mirfield via Stoke and Stockport picking up at Avenue Sidings.

    Looking forward to seeing your build of the above. Let us know which way you eventually go with the buffers. :thumbs: I have a vested interest. :avatar:

    My gut feeling is to go with the 19 inch ones as the Class 20 buffers and those fitted to later build 47's always seemed larger than the Class 24 or 25 ones. I've read through the pdf build instructions and think I'll use my Atten 907 solder station with pencil point iron tip for a quick in out on some of those tiny etch pieces. Also I'm not sure how necessary Delrin chains are with a motor on each bogie, after all my locos are hardly likely to get a high speed thrashing around and one mod I'd like to take up at some point is to fit the "holed" version of 3'9" bogie wheels if / whenever they become available. So yes I'll do a thread on D5018 if folk are interested. BTW I've fitted sanding gear to the 4MT and finished the bogie pivot plate too... just waiting for the replacement brake crank and expander rod to arrive from Scorpio then its chassis paint time after a good clean up.
