2.-When  sending  parts  for  replacement,  repair,  or  as  pattern,  the 

name  and  address  of  the  sender  should  always  be  securely  attached, 

and  full  instructions  explaining  what  is  required  must  also  be  sent 

separately  by  post.  In  no  circumstances  should  instructions  be  sent 

only  with  the  parts  as  they  are  liable  to  be  lost  or  damaged  in 

unpacking. 

3.-If  an  engine  is  sent  for  repair,  it  should  be  well  packed  in  a 

strong  wooden  box.  Cardboard  or a  sack  is  insufficient,  and  engines 

so  packed  are  liable  to  get  seriously  damaged  in  transit.  Packing 

cases  are  not  returnable  unless  specially  asked  for  by  the  owner  at 

the  time  of  sending  to  us . 

. 4.-All  goods  must  be  consigned  to  us  carriage  paid,  addressed  to 

"  Service  Dept.  "  Goods  returned  by rail  are  consigned  carriage paid. 

5.-As  we  are  not  manufacturers  of  complete  vehicles  or  other 

machines, 

only  the  engine  unit  should  be  sent  to  us. 

If  machines 

are  forwarded  an  extra  charge  will  be  made  for  dismantling  the 

engine  from the  frame  and  returning  the  components  that  are  not  of 

our  manufacture. 

6.-We  prefer  to  bench test  every  repaired  engine  before returning 

it  to  its  owner.  It  is,  therefore,  always  advisable  to  send  the  engine 

complete  with  its  magneto,  sparking  plug  and  carburetter. 

7.-When  forwarding  a  flywheel  magneto  for  overhaul,  send  the 

armature  plate  and  the  flywheel  complete. 

8.-Any  engine  or  sub-assembly  sent to  our  Works  for  repair  and 

not  paid for  within  12 months  from  the  date  of  our  estimate  or  from 

the  date  the  owner  is  notified  of  completion  of  repair,  will  be  dealt 

with  under  The  Disposal  of  Uncollected  Goods  Act,  1 952. 

9.-Repairs  and  spares  must  always  be  treated  on  a  cash  basis, 

unless  ledger  account  facilities  are  arranged. 

1 0.-An  extra  amount  must  always  be included  in  remittances  to 

cover  the  cost  of  postage  or  carriage  and  packing  on  spare  parts. 

This  is  5%  extra  up  to  £5  value.  Minimum  extra  is  6d.  Stamps 

cannot  be  accepted  for  items  over  1/- (one  shilling)  in  value. 

1 1.-When  making  remittances  by  telegraph  money  order,  the 

name  and  address  of  the  sender  must  be  included  in  the  space 

provided  on  the  Post  Office  Requisition  Form  for  a  private  message 

from  remitter  to  payee.  Unless  this  is  done,  the  Post  Office  does  not 

give  this  information  upon  the  telegram.
