The Forum for Gauge 3 Model Trains

Message: Interested in all types and gauges of loco. Have a number of 2 1/2 locos in various stages of construction.

I have a Precursor in 3 1/2 gauge, made to  H. Greenly's 3 1/4 design as described and detailed in Volumes I and II of the 1910- 1911 Model Railways and Locomotives magazine.

A detailed drawing by Greenly was printed in the Nov/Dec 1909 issue of MRL as a supplement- which I have as an original.

I believe James Carson of Cricklewood London manufactured castings for the Precursor in various gauges including a 3 1/4 and 71/2 gauge.
The 31/4 gauge I believe could be purchased complete, or as a kit of castings and materials for the home builder. 
To lower costs these kits used steel sheet material for the cab, the running boards and splashers. Unfinished castings for wheels, chimney, cylinders were available.
My understanding is that in 1913 Carson's ceased production of their model locomotive business and it was bought out by Bassett Lowke.
BL, I believe continued production of Carson's castings for the model up until WW1.

I'am not sure when my model was made and hope someone more knowledgeable may be able to help?
The model castings may be have been made by Carson's or to Carson's moulds by BL after take over.
The model seems to be to Greenly's plan dimensions.
As to it being a kit or factory assembly is hard to ascertain.
The cab and running board structure looks to be from press steel, although factory made
The lining out - now very faded is very precise and there is evidence of some gold ,water type ,decals 

The loco and tender has fully functioning springing and not dummies.
The tender has a separate water tank made from zinc and a cylindrical tank for a pressurised sprit fuel system. A cycle pump is used via a traditional cycle tube valve to pressurise the system.
A pressure gauge made by a German manufacturer is also on the fuel tank. The piping and primus type burner are missing.

The boiler is a fire tube type and not a Smithes, and may be a replacement or original.
The smoke box door doesn't have the correct hinges.
The dome looks to be a steel pressing.

Does any member have copy of Carson's 1911 catalogue.
Or BL 1913 catalogue copy , section A I believe shows the casting he was producing - including those of Carson's.

If anyone is able to help I would be grateful.
