One of the serial numbers is visible the other has been painted over.Also,the difference in components is also strange,I stand to be corrected.The bar tape and background colour where the badges are different on each bike.Both have nice old cranks that look the same sizes,one without markings and the other Simplex Proffesionel.The stems are different lengths ,one unmarked the other GB Kromo.The front derailleurs are totally different,one (Shimano 600)is adjusted via downtube shifters and the other has a lever to be operated by hand.Both saddles are the same and the wheels.I think the similarities may suggest the same rider for both Bikes,maybe one for road riding and one for Touring as it looks like one had a rack fitted.I totally agree the paint is beautiful.If it were just a case of an oily rag I would go ahead,but they're crying out for some re-chroming and real attention.If anyone wants some detailed photos,please let me know
