This rare Micron Celtic Mk I (1954) is almost new
and has been in my collection for more than 50 years.
The engine is complete and original.
The compression and bearings are excellent.
All the screw threads and slots are good,
and there are no marks or dings anywhere on the engine (see photos). 
The engine is easy to start and runs very well (see video).

I strongly recommend that the buyer should wait for my invoice before paying.
eBay sometimes overcharges postage.

I ship by registered post with tracking,
within Europe for £18 or anywhere in the world for £32.

Have a good look at the photos and video
and I’ll be pleased to answer any questions...
