I consider that the beauty of track bikes is that they are extremely simple and purposeful, which to my mind precludes messing them about by drilling holes in them. I have temporarily fitted a road fork to get round the problem, without any adverse effect on handling in spite of the greater rake. You only need a front brake, which is just as well because the seat-stay bridge is just a hollow tube which is unsatisfactory for mounting a brake on. Some people have made an awful mess trying to drill them. That said, there is probably enough strength in the fork crown to take a hole without any problem other than the aesthetic one. Whether you do it or not is really up to you -- it might put off some prospective purchasers when/if you come to sell it, but shouldn't substantially affect the value. I have purchased a track bike with a drilled fork crown, but paid a bit less because if I ever re-finish it I will have to go to the expense of filling the holes up again.

I am sure I have seen the very same bike that you bought -- a North Toronto dealer (forgotten their name) had several and I would have bought one had they had one in my size. Nice bikes -- Campag-like Gipiemme crankset as I recall. I don't know if they were Reparto Corse built or not and I assume they were not top-of-the-line because of the tubeset used.
