Handrail knobs!

Hello everyone, Seasons greetings to you all,

For a few weeks now, I have been steadily restoring a Brawa G4/5 locomotive that has been bashed about by a previous owner.
A previous request for parts on this website has yielded new buffers, cab steps etc. from Marklin (who now hold stock of limited parts).

I am now getting to the point where I need sufficient handrail knobs to fit the boiler and smoke box door handrails (12 in total). The Brawa knobs are plastic mouldings and are quite fragile. I would therefore like to replace them all with brass components. The dimensions are as the drawing attached below.

I have thought about using the Slaters O scale brass products but I do not know the dimensions and do not have any to hand to measure. If anyone does have some to hand and could run a vernier over them for comparison with the drawing, I would be very grateful.

Alternatively, if anyone knows of a suitable (UK based) supply of brass knobs to close dimensions of the drawing, I would be eager to hear from you

Thanks everyone,


Dave

I haven’t measured them, but Mahmoud from Dream Steam take a 1.6mm rod.
 
Essel Engineering might, but of you check the 16mm Association Web page, there's a list of very useful suppliers that might help
 
Whilst maybe not as tasteful as turned nobs, split pins (sometimes called cotter pins) can be used to a fair effect. I got my small brass ones at a show somewhere, likely from Eileens Emporium now sadly not around. Proops another possible option, though a search just now did not find any. Finally another option may be to bend some fine wire round the handrail wire, running this through a short length of fine tube to make your own. May not stand the looking glass treatment but from a normal distance done neatly works fine. I have used this method in the past when desperate to get a job finished.

Another place you might try is Walsall Model Industries - I've used their gauge 3 handrail knobs with success.

Hello Phil,
Thank you very much for putting me on to these. They compare extremely closely to my measured dimensions so I have ordered a pack!
When I receive them, I will feed back on how close they are!

Bit annoying really as they are located just a few miles from my house!... Have to see if Santa gets them to me before Christmas?
Still, thanks once again!

Merry Christmas all!
