Thanks both. 

The MR reducers obviously look the part, but are nowhere to be found on this little island fortress we have created.

Several US suppliers have them but I couldn't find any in Europe either so not just absent in the UK. They are a Canadian firm and importing from there is just the same as it always has been. To imply that Brexit is the cause is somewhat disingenuous. Pendle's stock a vast range of MR Slotcar spares but not this one. May be that nobody has asked for them before or they have been overlooked, try asking if they could obtain them.
