Britannia 5" gauge drawings

[norby]

Hello

A while ago I bought a set of "Norman Spink" plans second hand. It consisted of 21 sheets in total.

Recently I stumbled upon an old Norman Spink advertisement, which listed the 5" Britannia drawings as a set of 24 sheets.

A quick look in the Blackgates catalog also advertise a 24 sheets set for the Britannia.

Can anybody shed some light on which sheets I'm missing - if any. My set looks rather dated, but it hasn't been used for real in a shop it seems.

Currently I have the following sheets numbered 1-21:

1) Main frame and details
2) Pony frame, pump and details
3) Main axles and details
4) Coupling rods etc and details
5) Bogie and details
6) Pony truck and details
7) Brake sanding gear and details
8) Cylinders and details
9) Link motion and details
10) Reversing gear oil pumps saddle and details
11) Smokebox and details
12) Boiler
13) Boiler fittings and details
14) Superheater and ashpan details
15) Tender frame
16) Tender body
17) Tender brakes and w.p.u.
18) Cab and details
19) Footplate and details
20) Cab fittings clothing etc
21) Valves, ejectors and pipe details

Am I simply missing sheets 22-24?
Can anybody tell me what the names are?

Hi Esben,

I'm building the Modelworks 5" Britannia. Although I don't have a set of Perrier or Spink drawings myself, a contact who does offered the following explanation for the confusion that sometimes arises:

"It was the J Perrier drawings that were first produced in the early 1970's which Norman Spink had redrawn circa 1984. It was the redrawing process that introduced quite a number of errors. The original drawing set was 21 sheets with sheets 15 - 17 covering the tender. Spink's omitted redrawing of the tender as he substituted these with drawings from the Warnett 5" gauge 9F Evening Star model. So Spink's drawings comprise Brit sheets 1-14, 18-21 plus sheets 22-24 from the 9F. When Blackgates took over the Norman Spink business they were confused by the gap in the drawing numbers."

This all came about because I asked why the BR1A tender for my Britannia had handrails on the tender front - this is correct for the 9F BR1A but not the Britannia BR1A. It may also explain why the tender is slightly narrower than the locomotive!

It sounds as though you have the original Perrier set.

Hope this helps,

John

Hello John

Thank you for your answer! It all makes sense now.
If I look really hard all the drawings have the initials JP (all in one character) and what seems to be 73' written in the right hand lower corner.

BTW thank you for providing huge amounts of valuable Britannia information on your website.
After I found your website about 6 months ago I finally started working on my own Britannia.
