Yes the Wagon top B&O cabooses were great looking!! I saw many on the B&O's Washington branch ( now owned by CSX and host to MARC's Camden line ) during the 50's and 60's. I bought a beautiful Lionel B&O wagon top complete with smoke.
K line made a beautiful B&O wood caboose with smoke. I have one in C&O and it is gorgeous! FYI - the smoke unit gets hot and will melt the roof. My buddy had this happen to this very same K line caboose.... his roof melted big time ... beyond repair. My roof has a slight dent near the smoke unit as a result of the unit being place too close to the roof. I don't use the smoke unit anymore.
" Hot time in the old caboose tonight " LOL!
