John_Hughes Posted November 4, 2014 Share Posted November 4, 2014 I've acquired a set of Sharman wheels in excellent nick - the only trouble is, I have no idea what the prototype loco they were designed for could be. There are 4 off 22-spoke 26mm diameter, 4 off 14mm, and 6 off 16mm; the drivers have no crankpins, so clearly this is for an outside framed loco, and the 16mm wheels are obviously for the tender, so we're looking at 4-4-0 tender loco here, and presumably a passenger express. My first thoughts were one of the multitude of closely related GWR locos descended from the Atbara class but the wheel diameters don't seem to match so I now have to assume that the prototype would be from some other line, and here my limited knowledge has very quickly run out! Any suggestions would be most gratefully received! Thanks! Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted November 4, 2014 Share Posted November 4, 2014 How about a GCR Parker 4-4-0? The LNER classification D8 was an outside framed type, 6'9" coupled, 3'6" leading bogie, 4' and a bit tender wheel. Very close fitting splasher on the coupled wheels, so the slightly undersize dia. helps there. You won't find many of those on other layouts... http://www.lner.info/locos/D/d8.shtml Link to post Share on other sites More sharing options...
Tim V Posted November 4, 2014 Share Posted November 4, 2014 From the Sharman book (have you not got a copy), how about a City, these are only slightly undersized. Link to post Share on other sites More sharing options...
Adrian Wintle Posted November 4, 2014 Share Posted November 4, 2014 It could definitely be for a GWR Atabara/Flower/City - the drivers were 6'8" (26+mm) and the bogie wheels were 3'8" (14+mm). The tender wheels would have been 4'3", I think (16+mm) Adrian Link to post Share on other sites More sharing options...
John_Hughes Posted November 5, 2014 Author Share Posted November 5, 2014 Thank for the suggestions! I do have the wonderful Sharman book but we have the decorators in and all my railway books are in a pile in the spare bedroom! I'd thought about the City class and its near relatives (Badminton, Flower and the rest) - indeed, that was my first assumption - but for a prototype 6' 8½ the wheels seem a tad undersized, and of course they're far too big for the Dukes and too small for the Armstrongs. On the whole I suppose that City is probably the best bet. The D8 is a new one on me - somehow it just doesn't 'look right' but then the Sacre locos aren't quite my cup of tea. Make an interesting model, though! Thanks again to all for your help! Link to post Share on other sites More sharing options...
Il Grifone Posted November 5, 2014 Share Posted November 5, 2014 It's normal to have the wheels a tad undersized to allow for over deep flanges* (P4 modellers can stop reading here!) - it can be passed off as tyre wear. It's not going to be very obvious behind framing anyway. Or you can adopt the Tri-ang etc. practice of mounting the body about 2mm too high! Link to post Share on other sites More sharing options...
Adrian Wintle Posted November 5, 2014 Share Posted November 5, 2014 It's normal to have the wheels a tad undersized to allow for over deep flanges Or over-thick splashers - you can't scale down plastic or even brass to match the prototypical thickness.

John_Hughes Posted November 6, 2014 Author Share Posted November 6, 2014 Or over-thick splashers - you can't scale down plastic or even brass to match the prototypical thickness. Adrian Indeed, I'm very well aware of the fact that tyres were allowed to wear down within certain limits, and the splasher problem is one I'm having with a current build - once springing is applied to certain locos, the amount of leeway between the flanges scraping the splashers at the top of their range and the crankpins fouling the brake rodding at the bottom of the range is fag-paper small! No wonder some of the Buckjumpers had their brake rodding joggled so that it missed the pins, even on the Great Eastern's famously uneven trackwork! My fault for liking little Victorian tank locos, I suppose! Link to post Share on other sites More sharing options...
